strange leaf formation

Hello,

I am a newbie grower though I'm in my forties.

As you may see from the pics attached, the autoflowering plant I'm growing is forming some strange leaves. The plant is in good shape overall and I'm not having any problem with the other plants except for some leaf curl-ups which I believe is the natural outcome of heat level in the room.

1) Pictures are attached.
2) 1 sqm indoor. 400W HPS.
3) The plants are watered every 2 days with some superthrive addition. I am using florikan controlled release ferts.
4) The medium has %60 peat moss, %30 perlite, %10 lenoardit with some bat guano and bone meal.
5) The autoflowering plant is in flowering stage. One month passed since transplanting.
6) 82 F during light and %42 humidity. The temp goes back to 70 during dark. All other measurements pH, EC etc. are normal.

As I said, there is no sign of leaf burn, lack or excess of nutrients etc. and all other plants including this one seem to be quite healthy. I bought some autoflowering mix pack from a reliable seed company, and cannot give particular info as to its strain for the moment.

I'll highly appreciate it if you guys could give me some pointer as to what is going on with this plant.

Thank you very in advance,

Regards,

your temps can flex alot in a grow room in diff places and in diff times of days there are bunch of reasons why your heat can be to hi but it might just be lack of co2 but its not a def im 98% sure its heat stress bro

how is your ventalation i forgot to ask that also if you can take pics of your room inside and your vent setup that'll help also pics of the bottom of the leaves

Aside from the deformed leaves there is not much else wrong with them. There isn't an additive or fertilizer or other chemical available that can correct those deformaties and they will not affect the overall bud production so I wouldn't worry too much about it. 27c/82f degrees air temps are a little high, if that is the overall average temp in your room, however if that is the temps just at the top set of leaves then the temps are fine. The plants are in flower now, the best thing would be to just continue what you are doing and don't shock them by interferring with their bud production.

they say superthrive is like top dog for fert s or champion or some shit but the are to concentrated or somethan every time i add it i thought it was doin its job ...welll this grow its out and my plants are twice than with it ....

i have been using superthrive this grow and will not on the next i would really like to see for myself i should say my plants have been doing well for some of the problems i ran into early on so it may have helped with stress and it only takes a couple drops per the bottle so thats what i have been sticking to...But this is only my first time to flower so still have a lot to learn...But as far as leaf deformities my og #18 x skunk was like that but eventually grew out of it...first few nodes where like that...
