Although my tank is thriving, I believe my L. Glandulosa is suffering from some type of trace/micro toxicity. Both lighting and Co2 are calibrated correctly (40ppm+). I've been dosing EI for a while now, and I notice that some of my plants (particularly these) aren't responding well to Micro days. For now, I've discontinued dosing micros in an attempt to restore healthier growth.
