I've used the Fox Farm trio, mainly Open Sesame though for it's high P:K ratio (5-45-19 I think?), or something closer to that 1:1 for early-mid bloom, then BE for the finish... I also may cut way back on synthetic bloom nutes and run mostly organic PK through flowering, with light hits of MC,...maybe a dash of high %PK stuff if warranted... it's K, SO4 and Mn that play big roles in terpene production, so I want those loaded up during final ripening in particular,...
Yup, Microblast is the ticket,.. I dose weekly, also a foliar treat on occasion, even in early bloom; I don't hose the plant down though like when in veg', I'll "paint" the leaves to minimize exposure to the buds (usually, this is on the outdoor photo's, auto's only if the look needy); often, any foliar, even rain, can cause the pistils to brown out at the tips... Not a real problem, just bothers me-

.....For an actual micro's defc., I will use the Optic Foliar Transport with Microblast because that stuff works so damn well! Much of the micro's are sulfate based, so there's another plus-
