I would start with an indica like Oasis (nl#2) which is mite resistent and an easy cloner and very forgiving.

pH is not so much a problem if you only use 1/10th of what is recommended which is all they need though good point ibodro

NPK. Plants use the most N and then K as they are both balanced elements.

P stresses the plants into flowering faster though tastes awful and is very difficult for the plants to break down. I do not use it at all if I do not have to. N is about twice that of K.

My site GorillaGrow.org(anic) Home of Organic Chemistry Homepage has tons of info under resource tab at the bottom of the home page. From beginer to supercropping genetics.
