I suspect you might be giving too much fert. Wouldn't just advanced base nutes be enough? Do they really need B52 and voodoo juice? How about stopping those two and see what happens?

Thanks for your answer!

I already decrease EC level from 1.8 to 1.6. Now i'm waiting to see if my babyskank will "rise". I use B52 and voodoo juice because i follow the feeding scheduel from Advanced Nutrients website. Although i used half strenth nutrient solution as i saw on the website, I think, curling fan leaves is a sing of overfeeding.

Hope, that is it!!!

honestly, I've never seen plants wilt like that one before. Very strange. Come back to this thread and put up more photos, especially if the leaf appearance changes any. nice pics by the way.

Your EC is double what it should be, your plant is too young for max levels like that. Cut it waaaaay down, to like half that level. As the plant grows it will take a higher EC. You seem to have lockout combined with the overwatering that resulted. My advice would be to flush the system and run quarter strength nutes for a couple days until they perk back up. Then increase to half strength. Ease the light up a little as well, since the plants can crisp up as they try to recover. I've had this problem. It's much easier to solve with hydroponics. Ur good.
I am having to take my own advice!
