"Curved" leafes on Nirvana NL af

[Chrille]

Hello fellow cultivators. =)
I seem to have a little problem with one of my Nirvana Northern Light Autos.
The leafs seem to "curl" up on my smallest one (pic 1,2), dont even know if it is a problem, if anyone knows what the reason to this is i would be a happy man again.
The other 5 plants seems to be happy. =)

My setup;
Veg 400w MH
Bloom 400w HPS
Nutrient Hesi TNT and Hesi Bloom

Thanks !

(Sry for my bad english)

I'm no expert, so if anyone else responds believe them and not me.

I think that is a condition referred to as "canoeing". So searching for that term might help.

It is, I think, indicative of leaves transpiring more water than they can suck up. Caused by either A) minor heat stress (lights too low or inadequately cooled) or B) low humidity in the grow space. Likely B) if the meter in pic 3 is representative (ie. humidity sub 30%). Might want to throw a tray of water in there and try to get the humidity up around 40%. BWTFDIK?

Also, FWIW, my plants always have far greater problems and still finish fine - so yours look like they're doing great to me.

(Sry for my bad grammar, spelling, and attitude.)

Thakns for the respond Gilbert.
I will lookup canoeing like you recomended, i think that the second suggestion you gave with the humidity makes sense,
because i have had a little problems with keeping it upp and stabile.

Keep the temps below 84f and make sure the humidity is above 45 to 50.Ther really not that bad now but keep temp and humidity in check.

ur plant need more fresh air, more water, less temperature

I can only say what's already been said. But I'll add that it's not the end of the world and it's relatively easy to resolve so fear not. As soon as the environment settles they'll sort themselves out in a day or so.

I had the same thing on mine, I think that it was the heat from the HPS, I never could get those nice flat leaves, and always had a little canoeing, but they came through fine! I saw 26.9c on your thermo, that may be a little warm

The only thing I would add is this: If your growing situation doesn't allow for perfect environmental conditions (i.e. heat/humidity), don't panic. I've grown the same strain and saw the same thing. At the time my temps were in the mid to high 80's F and the humidity was swinging from 30% to 60% RH. I still ended up with a fine harvest (pics in my albums).
