so yea, the leaves are curling up and takes the shape of a taco shell. Any ideas what it could be? They are not discolored or damaged in any way. They are just rolling up. Sorry i dont have any pics. Any info would be greatly appreciated.

Hey dude. friend had the same problem, I believe. Plants looked healthy and green but they were curled, like a 'taco shell'. lol.

My belief was heat stress. He raised the light and.. Well, before i could see if that was it, he had to scrap the grow.

Could heat stress be affecting your plants? I'd like to see someone else chime in so i could know too.

Yes indeedy, taco leaves can be a sure sign of heat stress.

Hey thanks for the input, but i dont think it is heat stress. I have a 400w Hps with a cool-tube about 8'' away. Temps are always around a steady 75-77 degrees F. I did have the light closer about a week and a half ago, it was probably about 4-5'' away and i thought that was what was causing it so i backed it off to the 8''. Any other ideas what would be causing it? Maybe fert burn or somthing? Not enough ferts? I am totally stumped on this one. It doesn't seem to be harming my plant in any way. My buds are growing FINE.

not necessarily heat stress, but probably a low humidity issue. This is the plants way of trying to slow the pace of moisture loss through the leaves.

So should i put a bowl of water in the room? I dont have a humidifier. If i put a large bowl of water in there, will i beable to notice a differance in a week or 2?

taco leafes are either a sign of moisture stress as others have said(low RH, high heat, lots of radiant heat from the bulb) or a Mg def(!).

What nutes are you using?

I have seen mine do it with too much nitrogen. Used my veg soil recipe (by mistake) when repotting them for flower mode. I use worm castings so it doesn't burn them but they were super dark green and all new growth (only new growth) was curled like a taco shell.

Got any pics?
