Not sure what's happening exactly, but #2 started quickly started showing yellow and brown on many leaves. #1 also experienced this, but it wasn't quite as bad. I'm not sure what this is. If it's due to lack of nutrition or virus or underwatering? Anyways, I'm hoping they level out and recover nicely.
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
