everytime i get this point in my grow, i think i am at 5 weeks of flower, they leaves start to yellow on me, it usually starts outer part of the leaf and spreads inbetween the viens, the viens are green still but eventually they all die. i'm not sure if it's the age, so it is droping older leaves, or nute lock, calcium def? water is not an issue, nutes have been the same since first week of flower "open sesame" i just now switched to "bestie blooms" (after yellowing), both a fox farms product.. runoff PH is 5.5 to 6. Any ideas? it seems to happen to me every crop, sometimes all the leaves die all the way to the sugar.. it seems to greatly, lower yeild. watering is not the issue and too much water should not be the issue, at least with this plant, i have been very diligent. they are in fabric squat 10g pots. 1000w and a 300w led above her, good FAE. any help appreciated
oh, I have not tried cal/mag on this plant, but have tried in the past with no success to this same issue.
