HELP! Is this heat stress???

[MD to NC]

Here's a pic of my Easy Ryder day 10. Notice the slight curl on the leaves. I took this pic while it was still under 2x26w CFL. Temps were 79. Based on pics I've researched, it may be heat stress, but I don't see how. Maybe something else, or am I just paranoid? All help would be appreciated, thanks.

What's your humidity? I get similar curling in young vegetative plants when my humidity is below 40%. They've always recovered very nicely.

Looks genetic to me my friend. I have a few that looked like that during their first 3 sets of leaves and then they grew out of it... that looks fantastic for 10 days!

Don't stress my friend. Looks like it's just natural genetics of that strain/pheno...


Good question... what is your Relative Humidity? (RH) that is possible... but I don't think it's going to hinder growth or stress.

Heat...or do you have a fan blowing on them??? could also be from the cold air movement. i had that often but its nothing to worrie about its like kinda their goosebumbs when they get a cold fresh air flowin thru.

Another good point...when I incorporated 8" oscillating fans into my tents I noticed a similar effect

Dirtynorth right you souldnt place a vent direct blowing on them before they are 4-5 wees old. before that age they are sesitive for that and excatly that weird curling disapered at all Babies which were not threaten like that over here. But all that Plants never had props in the rest of their life. its really like a Goosebumb i think they show u brrr its bit windy in here.

thanks guys, yea i have a fan blowing on it which is giving it decent movement. maybe too strong this early. Gonna tone it down a bit and see what happens.
