I have a few plants that are about 2 weeks old, and they have been doing good so far but yesterday the ends of a few of the leaves have dried up and seem crispy and curled upwards. I have been using CFL's and been keeping them pretty close to the plants, so I decided to raise the height alot because my ventilation system is not very good so I was afraid they are getting cooked. I water them about every other day and all the other conditions seem good. The picture I have posted is pretty low quality but its the best I could do, you can see the leave at the top of the picture is dried and curled up. Any help or advice would be greatly appreciated.
