I have tried going straight to bloom nute at flower , I have tried using 50/50 at flower,
now I use grow for the first two weeks then switch to bloom for the duration of the flower cycle then at the last week I use only water.

I am up to learning to do better on my grows

I got lucky the other day I came across a place to get some DinaFem OG Kush seeds.

I know nitrogen reduces THC content , I hope it is used and washed out before THC production
takes place.

Hash_ stop buy and I will give you a big bud to smoke test . I got no lab to do test's.


peace bro

Thanks guys for the info.
Will use both of your recommendations
Using f.f. Ocean/Forrest and Dyna grow product
I think Hash had recommended I add more perlite to my soil
a while back, so been doing that with the 3 gal. fabric pots.

Have a hella of a time keeping my humidity up ( even w/ humidifiers in both
tents 2'w.x4'L.x5'h. grow t. 55-60r.h and 32-38r.h. In bloom tent
I've read it should be much higher, but I get by..

I have a monitor but really wonder just how accurate it is.
I have a couple of those testers where you add some supplement/ activator
to it. I should try that out.

since you touch on the subject here's a humidity chart. I don't remember what the numbers mean in the boxes but you just find the temperature your at and you want to stay in the orange. . . if one is running carbon filters they don't seen to work as good at high humidity so you have to compromise.

nitrogen reduces THC content? having to change nutrient regimen from veg to flower? 

 

personally, i say no to both. 

 

my strains are friggin CAKED with gland heads by the fourth week. if you had to remove

all the nitrogen before THC production would take place, the plants would die before finish.

 

i use the same feed, with ~100ppm N, from rooted clones until 4 days from harvest, when

they get plain distilled or RO every other day until chop. lots of folks are intensely successful

using a single feeding ratio through the entire grow, just google "jacks 321" for a bunch of 

threads, videos, pictures, etc. i hit close to 1.5 grams per watt this run, so it must be workin'!

 

hash_man, that's the vapor pressure density (VPD) chart

 

if you want to humidify your tents more effectively, put the humidifier in the room they're in,

not in the tents themselves. if you're exchanging the air properly in your tents, the room air

is the tent air. the room is the bigger volume, so humidify it directly.

Nitrogen is used to lower THC content of industrial hemp to meet THC level standards.

Lots of glands does not indicate THC levels, CBD rich cannabis won't get you high but has plenty of resin glands.

Carl Olsen is a friend of my family. Carl is an Ethiopian Zion Coptic Priest, we belong to a different Cannabis Church. Mr. Olsen also runs an Cannabis Spiritual site that welcomes all Cannabis religious users that can prove they have declared Cannabis as part of their Religion. They include many Christian sects that you have heard of and those of other faiths.

Carl Olsen keeps old volumes International Journal of Hemp on line.
Lots of knowledge in these old volumes if you only seek knowledge.




Effect of nitrogen on tetrahydrocannabinol (THC) content in hemp (Cannabis sativa L.) leaves at different positions

I. Bócsa, P. Máthé, and L. Hangyel

GATE "Fleischmann R." Research Institute, Kompolt 3356, Hungary


Bócsa, I., P. Máthé, and L. Hangyel 1997. Effect of nitrogen on tetrahydrocannabinol (THC) content in hemp (Cannabis sativa L.) leaves at different positions. Journal of the International Hemp Association 4(2): 78 -79. The effect of different levels of nitrogen fertilizer, of physiological age of leaves and of the interaction between these factors on the Δ9-tetrahydrocannabinol (THC) content of leaves from different positions on the hemp (Cannabis sativa L.) plant were analyzed by gas liquid chromatography. High nitrogen levels reduced the THC content of leaves, and older leaves contained less THC than younger ones. There was no significant interaction between these two factors.


Introduction
Hemp (Cannabis sativa L.) is a traditional and important raw material for the textile industry and is currently of interest as a wood fiber supplement in the paper industry (de Meijer and van der Werf 1994). A significant increase in cultivation of hemp in Europe is anticipated for future fiber production. Furthermore, drug-type Cannabis may play an important role in future therapeutics (Clarke and Pate 1994.). However, since one of its cannabinoid compounds is Δ9-tetrahydrocannabinol (THC), the psychoactive agent of the plant, its cultivation is presently limited. Breeders have developed low-THC and high-fiber content varieties, but some of these still contain a THC concentration verging on the EU limit for cultivation subsidy in Europe (de Meijer et al. 1992).
Since hemp has a high nitrogen (N) requirement, it is important to determine the relationship between N fertilization and THC content, and (for the purpose of analytical sampling) the interaction between N fertilizer and leaf position, in relation of leaf THC content.
Cannabinoid content of the leaves is known to decrease gradually from the top to the bottom of the plant (Hemphill et al. 1980). Nitrogen content in vegetative parts of the plant has been thought to correlate positively with its THC content (Coffman and Gentner 1975, Haney and Kutscheid 1973).

Table 1. Fertilizer treatments in mg/kg soil.



Table 2. The effect of nitrogen treatment on the fresh weight and plant height of hemp and on the N content of the phytomass.



Materials and methods
The experiment was performed using 5.5 liter pots, with two plants of the variety ‘Kompolti Hibrid TC’ per pot. This high-fiber variety has a THC content (0.5-0.7%) exceeding the EU 0.3% subsidy limit. Pots were placed in a glasshouse under ambient environmental conditions. A chernozem brown forest soil from Kompolt was used (Krisztian and Hollo 1992). Treatments are shown in Table 1.
Chemicals used for the nutrient supply : anal. grade NH4NO3, KH2PO4, KCl. Doses were supplied as solutions. Date of sowing: 22 April. Date of harvesting: 13 August. The lowest N level treatment was considered as the control.
The number of replications was six. Plants were grown until the end of flowering for staminate plants. Leaf samples were collected on 13 August in the following way: every leaf of both the staminate and pistillate plants was collected, dried at 40°C for 24 hr, ground, weighed, homogenized, and stored in a refrigerator at 3°C for 90 days. Leaves were placed into three groups: (a) older leaves that occur along the middle part of stem, (b) leaves from the side branches, and © younger leaves that occur near the top of the stem.
THC was extracted from the dried leaves with petroleum ether for 3 hr at RT. (Hanus et al. 1981). Analyses were performed with a Hewlett-Packard 5890 series II gas liquid chromatograph. Parameters of analyses were: HP-1 capillary column, 0.3 ID x 25 m length; injector temperature 260°C ; split ratio 1:70; detector temperature 300oC. Analyses were programmed from 190 to 265°C at 15C/min with an 11 min and a 5 min internal plateau at 235°C and 260°C, respectively.
Initially, an analytically pure THC standard was not available, so areas of THC peaks were used for characterization of THC content. The peak identification of cannabidiol and THC was carried out according to Hanus et al. (1981). Subsequently, CBD and THC standards were obtained and the original data were verified with these standards. The back-calculation of the data to an absolute value is analytically incorrect in our opinion, so this determination was not made.
The statistical significance of factors presumably affecting the THC content of leaves was determined by analysis of variance. The first factor was (a.) the leaf position on the plant, and the second factor was (b.) the nitrogen treatment.

Table 3. Analysis of variance of N fertilizer experiment (in a randomly arranged bifactorial split-plot experiment with six replications).



Results
There was a significant increase in fresh weight of shoot (80-130%) and plant height (28-39%) due to N supplimentation (Tab. 2). THC was highest in leaves near the shoot tip and on side branches, and lowest in oldest leaves (Fig. 1a). THC content of leaves of each plant part decreased in response to N fertilizer (Fig. 1b).
The decrease was significant in the case of the highest N dose (Fig. 1b). THC contents of leaves from various plant regions were significantly different, independent of the N level (Tab. 3, see: F-value of Factor "a") The other factor, N fertilizer treatment, also had a statistically significant effect on THC content of leaves (Tab. 3, F-value of Factor "b"). There was no interaction between the two factors (Tab. 3, F-value of Factor "a X b") in relation to leaf THC content.

Figure 1. Effect of examined factors on THC content of hemp leaves :
a.) THC content of leaves from different positions on the hemp plant (means of three levels of N fertilizer).
b.) Effect of N fertilization on the THC content of hemp leaves (means of three positions on the plant).





Discussion
These experiments show that the THC content of leaves decreases with increasing N doses. This phenomenon is favorable for agricultural production, because nitrogen fertilization will increase stem yield and simultaneously decrease THC content of the plant significantly. Additional studies are necessary to determine optimal N dose/ha, time of application, fertilizer type and the lowest THC content achievable under field conditions.

" . . Question..why did you do the 36 hour dark period?"

It's supose to make them not stretch as much . . . but I think it's going to be one of those be careful what you wish for things as now I'm thinking their not going to be tall enough


5days

Thanks Lakegal7 . .

9 days they haven't grown any taller for the last two or three days . . Freaky huh?

They are all 9-10 inchs 'cept one is 11" it's the plant I call the 'lemon pheno' it's younger buy 2-3 weeks than the others it's tall so had to flower it before it got too out of control, it also has alot of three and four bladed leafs I I think it's from stress, friend said it's a Triploid, LOL

here's some pic's of the budding flowers and stuff

That's interesting about the three and four bladed leaves.
So it's stress not genetics.
The third photo the leaves look super spikey to me.
Maybe it's just because it's close up.
I read about plants that are called duck foot leaves. I grew a mystery seed
not long ago and it had the duck foot type leaves at the beginning but then as it matured it started
to look more like a regular cannabus leave. Maybe my plant was under stress.It turned out to be a male
so ended up getting rid of it.

Yea, that's right . . these reverted back to duck foot I assume cause of some of the pH fluctuations it happens from I understand . . heres some pic's their on the bottom as well as some on top all the new growth is normal

not at all, you've got the roots restricted in those small containers. unless you're

doing multiple waterings per day, they basically max out once the container is full. 

 

i use "full container of roots before flowering" as a strategy for stretchy strains.

 

if you were doing multiple waterings per day you could pull a pound plant from a 

single gallon of coir.

 

EDIT TO ADD-- 

 

looks like you have thrips or some other insect doing damage to your leaves

good hypothesis, thats what I thought but all stoped stretching and not all are root bound and the lemon pheno is definitely not rootbotund.
I tend to believe the 36-hour dark period before flip had something to do with the slow/stop stretching, dude said to be prepared to veg longer cuz it will stop the stretch in its tracks and they would start flowering faster which seems like the case here not that I want shorty's, hell not!

LOL that's sawdust the specks on the leaves, I knocked as much off as I could but it's not hurting anything, I don't think
