Can you just use A*B for entire grow? Please answer!

Here’s my plants I have 6 in a 120 x 120 tent , They are coming along fine they are 3 weeks in vet and I’m going to flip them soon due to space in the tent all 6 have been topped, Anyway due to lack off funds I can only afford A*B the entire grow will my buds be okay come harvest?

Yes you can. I've grown plants out to full fruition using only base grow+bloom nutrients and Epsom salt. If anything you may get a cal/mag deficiency. If your growing in soil and you have some extra, top-dressing with more soil can also help feed the plant.
