i have 12 plants, about 6 1/2 weeks old, about to start flowering. i use tomato miracle gro nutes, i am fairly sure overnuting is not the problem, i pay close attention to the small amounts i use. i use only cfl's.

some of my plants are developing rust colored spots on the main stomata on the leaf

some are developing burns on leaf ridges

some leaves appear have a bluish tint.

most leaves are curling down slightly or are undercurling on leaf ridges

possibly N or K burn, P or K deficiency, or ph problem.

rep for any help to any of these problems
