Any chance I could get the link to that guide, in having trouble finding it2.5 is my lowest yield on the BB in 3 years, and I barely do anything to them for the whole summer, other than some training(and that's starting them under 100watts of t8 flouros...lol).
Everything is in the guide bud! (though I think you might have to dig for specific fertilizer...really I need to do an update to the guide)
