Got some leaves curling up at 10 days old. Running 600W MH about 2 ft above 4 plants, 17/7 light schedule. So far, just adding water @ 6.6ph in happy frog/perlite mix. Anything wrong here?
and if you're feeding at 6.6, and gettign a 7.2 runoff, I wouldn't sweat it too much. you'll be in range
yeah Bender that weird curl in the first pic, @ the base of the leaves...... first sign of heat stress IMO
Thanks for that. So if I'm 2 feet above should I raise my light? How much? I've read that you put your hand just above your plant and if it's too hot for your hand, raise the light - is that valid? At 2 feet it's ok for my hand. Thanks for that. I have been watering every day, I'll back that off as well.
