Peter's professional

I have been spending way too much for too long on Adv nutrients. I'm going to make a change. Now I thought I had my mind made up on GH flora series trio being a little more flexible than AN and less expensive. Now I came across a gr8 site with Peter's professional. I found 2 that seem like gr8 choices for base nutes. 1 for veg.

Then this 1 for bloom,
I have never used powder fertilizers before. I have heard some people rave about Jack's, Peter's, brands. I would love to hear some input from guys that are familiar with powdered ferts. If I went with the Peter's formulas that I have chosen would I need any mpk?(bloom boosters) or would my chosen base be sufficient?

I run Jacks 3-2-1
5-12-26 part A
15.5-0-0 part B cal nitrate
Epsom Salt.

GH Maxibloom.

Peters Profession 24-8-16 is exactly what I've been using for veg. I got a 25 pound bag very reasonably priced about a year+ ago when my last veg nute was gone. It has no calcium, but I use tap water and sought that out for my nutes. Out west adding calcium to tap is plant death (or at least magnesium deficiency)! It does have .35% Magnesium, but you could add Epsom should the need arise. Foliage special and some silica is all I use throughout veg, couldn't be happier. Don't buy the hype, cheap (relatively) nutes can grow quality buds.
