So i have rearrange the lights and spray the whole inside of the box white. Everything is going quite well except today i realized the small leaves (first two) of both plants are growing bit strangely. One of them is getting real dark and seems to be dried off at the tip. the other is getting really yellowish..i'm not sure the pic is clear enough..can anyone tell me what cause the probelm of this and how bad this situation is?? thanx

the plants are about 10days old by the way
