this is my 1st grow and am around 7 weeks in. i have a few concerns on a few things like some of the leave stems are down. i think the lower have nute burns but not 100% certain, also how long till i change to 12/12???? im in no hurry to change and want them to look more fuller before i change as stems are sprouting through off main stem....
i have not had many problems as such but would like some advice if poss. also on the tall one i am thinking of topping it, i have done 2 at an early age,
thanks for looking
