    Curling Leaves

    Hey everybody. So, I’m doing 2 plants in a DWC setup. I’m in a 4x4 tent, a 600w Viparepectra LED (which I plan to add another one in the next week), I’m running Advanced Nutrients Sensi series with Voodoo Juice, Dynazyme and Hydroguard. Last week I noticed some yellow/brown mottled spots on the lower leaves and fixed that after I corrected pH. I have an oscillating fan blowing over the canopy, not directly on the plants. The temp doesn’t go over 80 and humidity is at 50%. Almost all the leaves are curling on the edges of the plant on the left and only the lower ones on the right. This is my 2nd hydro grow, his didn’t happen on the 1st and I was in a smaller tent. Nutes are at 1/2 strength and roots look great. I’m stumped. Any help would be greatly appreciated. Sorry for the shitty pics.

    Leaves curling in at the edges could be a sign of heat stress. How close do you have those LED's above them? May want to consider raising them until the leaves are nice and flat.

      Thank you Cannabliss! The light I have is not very powerful, hence why I’m considering adding another one just like it. This thing is like almost 4’ above the plants and in a bigger tent. I’ve used this light on 2 other grows in a smaller tent and kept it way closer during veg and flower.....🤔

      That's interesting. The way the leaves bend up like that is a clear sign of light stress. That's the only thing I can think of. If you can provide a pic in natural light I can have a better look at the leaves and perhaps see if there's something else I'm missing. My other guess is perhaps Magnesium deficiency. Still, pics in natural light would help.

      Thanks again Cannabliss. It is weird. That light runs super cool and really is underpowered in my opinion for the size tent these are in. Is it possible I need MORE light? I’ll post some natural light pics below.

    More pics. Hope these are better.

      Since the bending is only on a couple of leaves and it’s not extreme, I’d just wait and see how she continues to do since we can’t figure this one out at this time lol. You said you fixed the pH issue, correct? How long ago was that? Perhaps give it a bit more time and see what happens?

      Dammit, now my babies are just drooping and about to fall over...😭, I’m thinking they’re not getting enough air in the Rez. I’m running an Alita 6L pump and a homemade air stone. Both of the Rez are 15 gallons with about 7 gallons of solution. The roots are fine, no rot, no funky smells. They’re a little tan because of he nutes. HEEEEELLLLLPPP
