since those leaves curled up before showing signs of burns it is to 85% heat stress causing this, not nutes.What does this look like? Heat stress? Nutrient deficiency?
i see crinkled Mylar at your grows walls, let me guess where a good part of your plants heat stress originates from...As promised: The first three pictures are of the curling plants, as I said before, the plants in question were on the "bulb side" of the reflector... receiving.. I would imagine, slightly more heat then the rest of the plants. The 4th pic shows two plants, the right one with curling leaves, and the left one in perfect health..getting the exacnuteme nute solution. The last one is an out of focus shot of the entire tray, just to help judge relative distance..but the light was about 6 inches lower until I moved it an hour ago, in an effort to correct the curling.
what lights are you using there? CFL, floro or MH?theres plenty of airflow and ventilation, I had to prop one of the weaker ones up with toothpicks because he couldn't take the wind...but the rest are nice and thick at the stems....I took the light up about another 10 inches, and watered them...if there not looking better in the morning I'll investigate further.
