use the 2-1-3 throughout...DONT USE 1-3-2 at the flip they will stretch like crazy and drop leaves...it is error to use high P ferts on cannabis in container gardening ..it is the macro used least by cannabis even in flower
outdoors is different ass P bonds and leeches quickly
2-1-3 can be found here...choose the one that includes all the micros or you will have to add those

I think anything that is balanced is fine. It's when you get into bloom foods that have wacked out NPK values like 1-5-8 that you get into trouble. Liquid Karma and crap like that although LK is nothing more than bottled water a .1-.1-.5.....that is if you believe and trust the stated analysis. $24/qt., are you kidding me? Who in the fuck is that stupid?
This biz reminds me of the auto title loan businesses we have popping up all over Texas, especially in the minority areas. Drill goes like this - you secure your title with the loan agency for cash ("....and I get to keep my car!"), for a "short" term loan that comes out to about 100% APR. Suckers will never, or can't afford, to ever pay off the principal as the interest payments are so horrendous.
Kite, looks like a great choice. If you're using that watch for boron toxicity. Sure is high in B. After playing with boric acid apps, I recently learned that some plants are really sensitive to it. I'm talking about as little as a pinch per gallon. Don't know about cannabis, but I suspect it is. It's one of those elements where plants require it for such processes as flowering but once you go over a certain threshold you can do some serious damage, even death.
Less is more,
