nitrogen? how do i get nitrogen to it?
I would just not worry about it. If it progresses start to worry....make sure you are feeding with pH'd water and everything should come along fine.um the soil is nothing special. its my first grow so i just bought evryday poting soil, and i dont know the temp. its a closet grow with a fan blowing on them at all times. it gets warm in there but not too hot.
You should have used seedling or young plant soil, reg soil can have strong nutes in which burn young plants, so it maybe nute burn x
Maybe a nute deficiancy then ?
