Hey pouyan,

Have you added any lime to your soil mix? Peat tends to be acidic as does bird doo. You might have a pH issue causing your nutrient problem.

pastor420 Reviewed by pastor420 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
