Too hot, too well watered, or too fast growing?

I've heard all three as reasons for the leaf twist (with hot being the likely choice to me as the twisted leaves are on the side that's not covered by the greenhouse poly film which cuts light to 86% and diffuses it to 60%). The soil is not saturated that I can tell (20G mesh container), it hit 106F outside today and this plant gets a bit more direct sunlight than the other 3 (none of which including 2 of the same genetics show any twisted leaves) and it has lately been the fastest grower by far.... so any thoughts /opinions / comments? Perhaps it's something other than these three. Aside from the twisted leaves the plant looks amazing, I just suspect it's saying I'm hot. and will continue to grow just slower on the 102+ days? (thankfully in the next 10 days it will go back down to just the upper 90s


Thanks people!

they look cooked.you must lower temps. maybe add airflow

Cool, thanks I need to trust my instincts more. After the temps dropped into the 80s I played a bit with placement, if that doesn't fix it tomorrow (only projected to hit 100F ) my next step will be to add on / extend the film to cover the western side as well. You can really see the difference between indica and sativa genes, the pure sat which gets even more sun isn't bothered aside from turning leave "flaps" up.... if the extra film doesn't help I'll then add a box fan, but I suspect that filtering the heat of the sun will do the trick... Just a fine dance between sun shielding and airflow when you're surrounded by all sides by either fencing or a building and your fresh air is over 100F... Aside from the one not enjoying the 106F weather (I swear it was fine 2 days ago at 101....) with mostly full afternoon sun, the four girls look happy as hell, quite looking forward to seeing what they do now that flowering seems to be starting (first outdoor, first time using 20gallon smart pots, and first time with the genetics, go lack of experience )

Once again, thanks

I'm glad I saw this, one of my girls inexplicably got a few "wilted" leaves and I really couldn't get a lot a help as to why but mine look exactly the same. I moved her a little away from the plastic of my little DIY greenhouse a few days ago and she seems to be recovering well. The greenhouse itself is very well ventilated with an open "door" and large screened windows.

every grow is different. you will get the hang of it. stick with it. best of luck

air flow is key in a gh. I use shade cloth walls.
