What kind of light bulbs are you using and how old is your plant? Because mine also did that when even my cfls were not even touching and temp was good. If it is a youngen ( 0-4 weeks old) it will need about 2 inches of space from a cfl. If its anyother light source also try to give it more clearence and see how it goes.

im using CFL's and there about 3 to 4 inches away fro the leaves and i mean it is growing fine just the leave tips are yellowing and my plant is like 3 weeks old. i think it might be my nutes so im gonna re adjust them today.

make sure the pH of ur water is ok

yea probably the nutes are too strong.. mine did it too.. i transplanted to soil and its green now
