No i kept them at like 27-30 degrees celsius all the time, i had both low ryders and blueberrys. I had just switched the blueberrys to a 12/12 cycle like 2 days ago but that cant be the cause of it because the low ryders r dying as well and they were in separate grow rooms. I watered the blueberrys once a day since i switched to 12/12 and divided about 1L of water between 3 of them everytime i watered, and the lowryders i watered twice a day with a little less then a liter between them each time, i have 2 lowryders btw. The reason i hve trouble understanding how this happened is because they were doing great before and the only thing i had changed was the light cycle.
