I am still an uber noob... this will be my third PF Tek grow.
I will be putting my jars together this week.
I am wondering if anyone has any suggestions regarding some additives to the standard recipe?
In my second grow, I tried some worm poo in some of my jars... not really convinced that it was helpful at all.
I have read about gypsum, lime, and phosphate being beneficial.
I work at a garden centre, and we haven't been able to find gypsum for our shelves for ages.
Due to the lockdown, I am basically limited to what I can buy at my garden centre, or at a grocery store.
Any thoughts are greatly appreciated.
Thanks so much!
