My bad, I forgot to mention that I added 20% organic perlite to the soil. The light is so close to the seedlings because they had been tilting toward the light which at the time was HPS. Once I realized how much of an impact HPS had on autoflowrers, I immediately went online and purchas a new 600w metal halide bulb. This morning I noticed that two of the seedlings starting tilting towards the opposite direction of the last light (assuming it might be because MH is working better?) so I brought the light to 18 inches away from the seedlings. Although heat was an issue, I don't believe it's what's causing the leaves to bend. Any other possibilities?
I have five auto flower seedlings in my grow tent. They're about 8 days old and some leaves are curling downwards. I thought it could be from over watering so I stopped watering for two days when an inch deep into the soil was dry, i watered it again. It's now been 48 hours and the soil is getting near dry again. I don't think it's from overwatering but I wanna make sure before I go watering again. I have a 6inch fan at the bottom of the tent blowing in air from the outside, and another toward the top on the other side of the tent blowing air out of the tent. I had an 600w HPS in but changed it yesterday afternoon with a 600MH. The light is one foot away from the plants and the soil is 72-77°f (measured with a solid thermometer) and the tent is between 70-77°. I used Foxfarm soil soil it's not the soil, and I have used any fertilizer. Any help is much appreciated, thanks for your time!
