Ok, flushed in the bathtub for almost 10 minutes under the tap had a ppm of 800 in that runoff. Then put a full dose of nutrients which came out to 1600ppm on my cheap ass pen. Going to let her dry out and see what happens next.

Is that the runoff pH and PPM or the nutrient solution pH & PPM prior to giving to the plant? Also, what grow light are you using and how far away is it from the top of the plants?

@Angrybird Growing I'd bump up the feeding. In flowering I usually aim for 1000-1600 PPM. Your plants may just be hungry.

@Mr. Grow It OK so my plan is to flush that plant tomorrow with tap water in case I have any other issues going on in the soil, then give it a measured feeding. Going to aim for 1200ppm with the Advanced Nutrients I mentioned before.
