It looks like iron is locked out and/or pH is too high.
Right...as I notedI always thought with N been the most mobile stole from the low classes to give to the upper classes, sry, leaves, like a reverse robin hood.
Came in this one late but, Church got this with the nutrient "cock blocking"......Next page has the OP giving the pH at 5-6 and I would be pHing to 5.8 and letting it rise to about 6.1 - 6.2 before adjusting down again. So maybe a tick low - BUT not the pictured problem!Aren't you supposed to use equal parts of A and B? Too much calcium nitrate will lock out magnesium and iron.
Try using the A+B in a 1:1 ratio and stop using the bloom booster.
