Just got home from the weekend and 6 out of 9 of my plats are wilted completely. THey have been on a steady watering schedule with earth juice grow products. They are 4 and a half weeks. They are under a hortilux 400w metal halide conversion. The room gets plenty of ventilation. Just dont get it. I raised the light up and gave them some more water but I dont think thats it. Please help if you can.
