I know you said your on a budget of nil, but you need some better neauts than what your giving them. I use botanicare pro grow, pro bloom, liquid karma, hydro-plex, bud candy, and clearex to flush. This gets great results but is a bit expensive. You could get by with pro grow, pro bloom, and liquid karma. About $60 bucks total for a quart of each which would more than do for your grow of these plants. :rasta:
