Leave curling tips dieing

I'm sorry but I cannot provide a picture no camera
1 month 2 weeks veg
Watered when first knuckle is dry


I just need some general problems with this if no one can provide info just shut this down. Also this is a extremely cheap grow poor soil (May be the problem not sure) semi poor drainage no Nutes all organic it is also indica from what I can tell fat leaves it's small as we'll only about 8 inches poor lighting in general this is an experimental grow and just for some personal bud

with out a pic its hard to even say what it could be, an from the sounds of your setup it dont look goood id try an throw a pic up otherwise Good luck.
