What is the NPk value ? Does it has enough n? Is it close to a 1-3-2 to flower and your veg a 3-1-2 ? Check these to start. IMO had trouble with those specific nutes having to much p and k many other reasons as well. Hope it helps.

What kind of water are you using? Did you add any dolomite lime to the soil? That has cal/mg, adding some extra N and mg wouldnt really hurt them to be safe it could be either or.

Epsom salts contain mg add maybe 1 tbl/gallon, it for sure wouldn't make any probs worse. N and mg to be safe imo.
