lol, I know all of the ec breakdowns brother. All ya have to do is ask.
You also are close to what Kraven is using in flower, but his recipe is designed to be all the way through flower to the end where yours is broken down in stages from veg to the end. My recipes I assure you are way less than most.
In or on? lol
Personally I'd never recommend them. They typically sit too wet and if your temps are even slightly cold your gonna rot seeds and cuts both. They are an equal opportunity killer of cannabis.
That said some people love them, and have the habitat/environment to use them with some success.
I find things that are inert where there are no guessing games as to what is at play are best for seeds and cuts.
