Just wondering if anyone can help me, newbie grower under 600watt lights.....Leaves are curling up at the tips underneath themselves. too hot in my growroom? light too close to plant? underwatering? not sure so any help would be greatly appreciated!! :rastasmoke::jointsmile:
put ur hand under the light where you have ur plants at the exact level the plant is at if its too warm for ur hand its too warm for ur plant. Lack of water makes them wilt not curl and dry
Hope this helped!:hippy:
Leaves curl up when they are too hot, so your light is probably too close. HPS should be 12-18 inches away from the top of your plant and try hachimans hand/heat technique. Tried and tested!.
