Over fertilization or?

Is what I have here just over fertilization or a deficiency of some sort? Single female just started her 6th week of flowering. She's in a 6 gal bubbleponics setup. Any help or ideas would be appreciated.

Fyi this only seems to be the top area of the plant that is affected by this issue.

its your ph its starting to get fucked up check on it

same things just happened to mine add some nutes with some high phosphorous ratio and youll be fine

I agree, pH imbalance seems to be the diagnosis. Looks like it's impacting the cal-mag uptake, maybe also Phosphorus but it's hard to say. Get that dialed.

Thanks for the 411, I've got her in 5.8 water now. figured a day or two with no nutes can't hurt her.
