Hi all... Can someone with more experience take a quick looky and let me know what you think. The lower, large leaf is curling but the other leaves are not. Out of 3 plants, only one is doing this so I'm not sure if it's heat or because it's just a "lower, large" leaf. The plant is 18in from the 400 hps bulb and does not feel not when I put in hand in under it.

The plant in the picture looks yellow but it's only the photo. It's actually a dark healthy green.

Thank you in advance.

Veg: 11 days
System: DWC
Temp: 75-80 F
Humidity: 35%
Dyna-Gro Nutes @ 460ppm
pH: 5.8 - 6.0

Curl from heat man but not very bad. Strange tho 80 is not overly hot but it must be a sensative strain. I see heat stress on most my indica sativa hybrids and pure indicas at about 83 degrees.

I forgot to mention that the strain is Aurora Indica. The heat has gotten up to 82 but stays around 79-80 mostly.

After reading your post, I diluted the water and lowered the ppm... It's about at 400 now...

Thats strange because I was told by another very experienced member on this forum that I should/could be giving them nutes between 400-600. I know I have to give them at least a little right? It can't survive on water along... right?

Does anyone else have any suggestions?

yeh you should be given them nutes,,if you were growing in soil then the first 3-4weeks with no nutes (depending on what soil u use) is fine,,,your not growing in soil so you should be giving them nutes,obviously not full strength yet,,ya plants just look heat stressed....peace

Hi Cheetah, I think you could be right. I think it's a combo of both heat and over nute-ing it. It wasn't doing this until I up-ed the nute about a couple days ago. No need to apologize, I appreciate your help.
