Also, peat moss is very acidic and you may see lockouts from that if you did not lime, but ATM your main problem is overfertilization... the fert you are using isn't properly balanced for cannabis, look up cannabis-specific ferts and try to find something that mimics them, or just buy one.
I agree! but then again i always do!
Tomthehippie Reviewed by Tomthehippie on . Nutrition Deficiency -- I think iron? NEWBIE I NEED HELP i've attached 3 photos of my plants. At first they were doing fine but the growth is now stunted. the lower leaves are turning yellow and falling off so i added a fertilizer (15-15-15). I think i overfertilized which caused some of the leaf edges to burn. Regardless of the fertilizer, the soil has perlite, sand, peat moss, and a little bit bird manure. It is very spongy and seems fine, but the plants won't un-stunt their growth and the leaves continue turning yellow despite the fertilizer. Any Rating: 5
