I'm about 3-4 weeks in on a single plant in soil. The cotyledons are yellow and the stipules are about 1/8" long now. Judging from the pics on here, it's got the long narrow leaves of a sativa.
I'm about to start feeding it now (Thx LudaCris !) and I'm looking for some 20-5-5.
I haven't seen that ratio at any of the local garden centers...what else is it used for ?
Also, they have 5-1-1 fish fertilizer. Can I just mix it 4X stronger to give me 20-4-4 instead ? (1 tbsp/quart instead of 1 tbsp/gal)
Otherwise it'll have to be something like 20-20-20 general purpose fertilizer.
I've got some fresh pics in my grow thread (link's in my sig)
