so can i use jacks all purpose all the way from veg to flower? would anyone recommend doing all purpose in veg and use both all purpose and bloom for flower?
I use inexpensive fertilizer (Grow More Sea Grow) like Jack's, and mix all purpose with flower to get custom (scalable) NPK ratios in flower. I made
a spreadsheet to see the NPK ratios that result from things like calmag, Liquid Karma, and mixing ordinary fertilizer products.
I'm in soil. If I were going to try Jack's I'd use Citrus Feed in veg, and mix All Purpose and Bloom Booster in flower. But, All Pupose should be good in veg. I'd try to get an NPK ratio of 1-2-1.5 in late flower. I'd scale my way up to that in early and mid flower. Maybe use Bloom Booster's 1-3-2 ratio once in late flower as a "booster." But, otherwise, I'd mix it to keep the P lower, maxing out at 1-2-1.5 to 1-2-2 at the end.
