I'm going to take a stab. Personally I think it looks like potassium is the culprit, that would be my guess. Keep in mind this is simply an educated guess. Take the information as you will. I encourage others to offer up an opinion also.

either up or down, and I'm thinking it's a tad too much bloom right now, although I could be mistaken. Seems to me your P might even be throwing everything out of whack.

My guess is K is either high or low here, and P might be involved/interfering. Bringing up the pH a tad might help some also. ie. 6.0-6.5

How well are the roots being saturated here? Also, how often are the plants allowed to dry/cycle wet to dry... Pot size, ect. Lots of unknowns here. This could alternately be a causative factor.

Needs more information.
