Not all plants are showing this but a few are. They are under LED. Fed 6/9 + 1g epsom salt twice a day as they are in small pots. I have been chasing this deficiency since they were smaller. I tried scaling feeding back on the problem plants from 1.2 EC to .9 and worked up - same problem. Dark veins, interveinal chlorosis then these brown edges form with downward hooking. Growth is not right. Temps @ 80, RH 65%. RO mixed with tap for stability pHed to 5.8. Roots look great.
