The leaves look thick and droppy, but they also look dark green... idk
Last time I accidentally watered with x10 the recommended amount of B-52 (Advanced Nutrients). Could that be related?
It looks like to much nitrogen see how it has that slight blue tint and the texture feels waxy I would flush them let them sit for a couple day then reintroduce 1/4 neutrents that you would normally give it and work back up to what you usually give it
Absolutely! Flush with straight RO with run-off. When watering with nutrients always use %75 strength. Make sure the nutrient solution is of PH 6.2, And I will go even further and say every third watering use straight RO.
