This could be it. Recently upped the intensity

I see a little burn at the tips of leaves. They also appear to be very dark green. I would say your ec is high and your causing feeding problems. More is not better with weed plants. Most prefer ½ to ¾ of what the feeding institutions say to feed.

I would do the math and feed at ⅔ ¾ strength and look for improvement... or maybe you have cut your feed back 2 much...

What all are you giving her?
