sick plants...

[numbinside]

not quite sure what to search for. Plants were doing fine for about 2 weeks.

soil mix is 1/2 MG organic (I know but oh well), 1/8 peat moss, 1/8 perlite, and 1/4 earthworm castings. Using 6 42w cfl's (rated at 2700 lumens each so 16,200 lumens total) in about a 5 sq ft grow cabinet. Lights about 3-4 inches away from plants. Everything was fine till about a week ago, one plant started to yellow a little, now all 3 are starting to curl and yellow. 2 of them, the tips are curling under a LITTLE,but the sides are curled upwards like a half pipe. one of them has yellow spots and the tips are yellow(some)

one just has real pale green/yellow leaves but is growing a little faster than the others.

sorry if its been asked, searching never brings up anything regarding my actual questions....

Ok we will need a little more info to help you out. What fertilizers are you feeding it and on what schedule? How old are these plants? Are they in Veg or Flower? Also a picture would be very helpful.

Did you add lime to your soil mix?

curling up of the leaves can be heat stress or too many salts. Flushing would help the salts. Any pH or PPM info on the run off water?
