Leaves Going Brown/Crispy?

A couple of the leaves on my babies are going brown and crispy near the end of the leaf. They're about 3-4 weeks old. I'm thinking maybe this could be over/under watering or something? Can anybody help?

without pics its hard to tell, could be nute burn, could be lights to close. post some pics and maybe I can help

I'm guessing cfl's ... I know all too well how hot they run. I love em but they are a bitch to keep cool, in a small area.

Without pic's or more info, I reckon you ought to bring the temp down... Move more air through your grow room and freeze some water bottles.. like several 2liter bottles and rotate them through.

Good luck.
