Quarantine Hydro

I switched out one of the t5 lights for my 1000w cool tube. This seemed to worsen the twisted leaves and brown spots that were appearing. I kinda lost track of the cal mag i gave them and suspect it may be a calcium deficiency. I added another 250ml to the 100gallons of nutes and we will see what happens. The plants under t5 still seem to be fairing a lot better. 1000w is at 28" . And tent is at constant 65-75°F . Humidity is at 65. I dont suspect heat stress.
