These girls seem to be struggling. They're either getting burned by nutes, or lack there of. Or PH? Not sure, but this keeps happening in my past 2 or 3 grows and it's frustrating AF. I'm really hoping my Jillybean Lime plants don't get this.
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
