The gals are stabilizing overall. I'm thinking of moving back up to 3 gal pots. Maybe that was the issue? Anyways, #2 is looking about ready to chop in a week or so. I'm going to start flushing her, but #1 doesn't look nearly as close. So I'll keep feeding nutes to her.
Measure everything you can going in... pH, EC...whatever you have the tools for. Doesn't look like overfeeding with your nutrient numbers. Best of luck mayne
