Feel like I should have stayed in school or done science. Potassium And flowering

[Lulu28]

How do I know when to switch to flowering? I dont really have a size restriction. And how do I understand which is the better potassium from these labels?? Is %w/w the same as %wt/wt

With photo plants one switches the light when they are ready, at least 3 weeks of veg,,, when they get big enuf, and still room for stretch, flip em!
As to the chemistry question, when I was in school they made me take ,,,, typing instead of science. Ever wonder what might happen to type writer in front of a disgruntled teenager,,,, lets say nobody else ever used it!

I was in science once or twice, the bunsen burner was a good cigarette lighter.

I think in this case w/w is same as wt/wt. Look for three numbers, that's your N-P-K. K is percent potassium.
Fertilizer on the left will also add sulfur, the one on the right will not. Not sure either ones better or worse.
I have used potash before, works fine.

Hi Lulu28 You may not have cared for science in school, but if you want to grow top shelf buds, you have to learn how all things Cannabis-related work. The https://www.growweedeasy.com site will give you the best recommendations of what to use to feed your plants and when, when to switch to flower, and answers to the other 75,000 questions that you'll want answered as you learn to be a really good grower. I think most of us do our best learning outside of the classroom anyway.
