My bad, I'm running
Advanced Nutrients Sensi Coco A + B, B-52 and Voodoo. 3/4 strength from recommended feed chart.
Canna Coco and perlite 75/25. All plants have had zero problems up until I was giving them too much light. The plant that is having issues was closest to the light (it was also by far my strongest to start, that's why it's so weird to see her struggling). All started at 1 shot a day, now feeding 3 shots, one 15 minutes after lights on, one 7 hours later and again 7 hours later. Dryback readings seem good. Plant is uptaking water the same as the rest of the plants. Just weird that the tallest happens to be the only one not doing better. EC doesn't seem to be spiking on her either. Temp is 80F day 73F Night Humidity 55 day 45 night.
