Hi GLN.... this sounds like a smart move IMO, go for it! There's been a great deal of back and forth about the amount of P in your formulations amongst the growers I know here.. The general opinion is that it's too light on P, BE is too heavy on K for early-mid bloom where higher P:K ratio is better, something like the old Red Line was... I'd love to see P included in SC, at a high % than K or at least even with it more or less.... BE has so much K bias you have to be careful with the MC because of potential toxicity, which I do see on occasion in the Infirmary... I always considered BE to be a finishing bloom nute, and use it as such...

I would also very much like to see you guys come up with a good micronute only supplement, though I'm not sure that's possible for chemistry/formulation reasons..? My favorite is Earth Juice Microblast (cheers

), a liquid the the broadest coverage I have seen to date... My gripe there is it seems to not have a long shelf life after open, despite being well chelated,... it starts out a clear dark green when first opened, but after a few months it begins to oxidize (O2 exposure), and starts to go "rusty" in color, literally I think, and develop some PPT's.... a dry formulation would be excellent if it could be compounded.. There is a glaring lack of these type products on the market, trust me, I have looked... Micro's defc.'s are far more common that many realize, and are difficult to fix at times because what products they may have don't have enough, and/or force the introduction of other nute elements that are NOT desired or wise to pile on! I swear, if you made this, and available in EU especially (lousy choices over there for micro's), I could sell several bags a week in Sick Bay alone-

I use micro's regularly all through the grow, they are a bitch to fix often, and their lacking may not show outwardly for a while but still mess with the plants performance as well as other nutes' metabolizing.....
