Second opinions on growth problem..

I believe this is Phosphorus deficiency... not 100% sure.. might be nutrient burn, the plants had been taking constant feedings well, so i bumped up the nutrients a bit. Since this problem i have flushed them with clean water, and i'm going to hold back on the feedings for a bit.

I also thought it might be mold, or a parasite, but it is one plant with the problems, and there is no topical residue, or growth (other than cannabis)

This is a Haze Automatic, 30 days from seed, and it is well into flowering.

looks like a calcium deficiency to me. but you may want to neem oil them to get rid of any critters/fungus to be safe.
