-- what dosage are you doing on the

bloom boosters? What other nutes besides them? What soil brand? .......You have more than one thing happening here,.. those boosters are way fierce strong, and as you see they can burn quickly,.. too much P and K will interfere with the uptake of other nutes, particularly micronutes,.. yellowing is worst at tops, right? that indicates a micronute defc. in play, and those spots look like Mn defc. to me,.... those nutes are also highly acidic in solution, did you adjust before feeding?
So, the question is if this is a simple lack-of type defc.'s, or a pH lockout of them,.... overly acidic soil will also lockout P which can show similar yellowing, spotting,.. but usually not in this pattern... all this brings the question of what the actual in-pot pH is! Without a solid reading on that, adding more bloom nutes, micronutes (yes I know they have micronutes in them-

) could make matters worse, not better,.. Now the pain comes from how to get a good reading, if you don't have a quality pH probe made for this (Accurate 8 is a good one),.... no probe, then it's a run-off check, which in general is lousy for accuracy... We do have an improved method and calculation here in the highlighted section above this one,... So let's see what you say about dosage and go from there,.. worst case, you'll have to do a flush, but you can do the run-off pH test before that since you're going to be saturating the soil already,....
