Leaf Edges Curling Up!

Hey guys, just wondering if you'd take a look at my plant.. I'm getting some curling on the edges of the 3rd leaf set. I'm running 6 x 26 watt 6500K CFL's (18/6), FoxFarm Ocean Forest soil, with no added nutes yet, JUST regular water with a pH in the low 6.0's. Temperature stays around 77F in light hours, and 72F in dark hours. Humidity typically stays around 42%. I had a small fan running 24 hours a few feet away from the plant causing a slight twitch, just to cool it a little. I just recently moved the fan closer, and shot the air in between the plant and the lights, as seen by the photo, and still gives the plant a little twitch The fan now shuts off in dark hours, because I thought the curling was due to stress from the fan.

I really don't think heat stress is the problem; as you can see in the photo, the lights are plenty far away with enough air to cool them. I thought maybe the 24 hour fan might be stressing it out, which is why I cut the hours back. Could this also be nutrient deficiency? I'll eventually be using FoxFarm Grow Big, Big Bloom, and Tiger Bloom according to their soil feeding chart. When should I start the feeding? It's only been in the Ocean Forest for 14 days.

Isn't it strange that the first leaves turned out fine, and the new sets are curling?

Take a look at the pictures, and let me know what you think. ANY help would be appreciated. Thanks guys!

to me it looks like heat stress, sometimes the leaf edges curl like that.....maybe its to much light to soon...i run 2/ 30 watt t-5s on my sedlings to keep em safe

Hmm. Heat stress even though the CFL's are about 6" away from the plant?

i dunno , put the back of yur hand up to the canopy and see if your hand feels hot.....if it feels hot on yur hand then it wiil on the plants...i dotn really see anyhting wrong with it asides from the lil curling


as for feeding id give it another week or so, when it starts to turn lighter grren/yellow then it needs food

hey your leaf structure isn't symmetrical. kinda kool

It definitely feels cool under there, especially with the fan cooling that air a little bit. That's why I have no idea why the leaves are curling. It's my first grow, so every little thing makes me wonder lol. Thanks for the input man!

It's symmetrical. Just a trick of the camera

thats good to hear, thats one thing you know aint the prob then...jus let it ride and see what gives.....might jus be a lil phase, it looks pretty healthy

Humidity, plants at this age want humidity around 70%. Find a small humidifier or set out some bowls with paper towel draped in them to wick the water out and evaporate. Other than that it looks good

Thanks Massah, I'm on it.
