Jacks is fine up until harvest. If you wanted to alternate from an all purpose veg to a bloom formula for flower, that's cool too. I use a similar product called maxsea 16-16-16 throughout veg and flower with killer results.

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.

I used Jacks last summer outdoors, in a 16 gal coco hempy tub + a couple 2gal buckets. All purpose during veg and just Bloom booster during flower. I thought the results were really good. I've heard of using only the all purpose for the whole grow and I'm sure it would work. I run a mostly 1-1-1 ratio during flower with control release ferts. No matter what you use just don't over do it and the results will be fine.

I have used Jacks Citrus FeED only for many crops now.
Start to finish it is all I used, I love the simplicity and the results...keeps the leaves nice and green right 'till harvest, fat juicy buds galore.
Easy peasy lemon squeezy!
