Looks like it has a little heat stress, but still very healthy looking for being in high heat all week.

Yes light heat stress but nothing to worry about. Mother nature has always taken care of herself outside.

Heat, RH or overwatering? Or alltogether?
Hey my fellow growers! The grow reached 32Celsius the last 2 days in the last hour before going into night time. On that time RH goes down to 32% and this seems like it's stressing this lady a bit. Yesterday fed her nuts - maybe a bit too much? Thank you for stopping by!

Starting Training
I'm currently worried about my older plant set that seem to be constantly having the leaf edges curl and seem to be a little droopy and a little too dark green. Also I feel like I should be doing some sort of training. I would love to have some feedback on what you all think. ✌️

What’s causing my leafs to curl?
Leafs are curling inward on new growth. It’s not exclusive to the tops. It’s only 2/4 plants. It’s still growing fine as it’s my tallest and biggest plants. I’ve adjusted my light down to 2/10 as my first fix and moved the fans around. Any suggestions?

Leaves curl on upper new growth and mid but not lower.
I’m using the canna coco line except boost, looks like phosphorus deficiency. I just lowered my a and b 0.7 ec and added 0.3 of pk for a total of 1.0. Is this phosphorus deficiency and do you think my changes will help. Leaves are a little dark shinny and the shape is odd.

Leaves curling upwards
What could this be? I consider too intense lighting, could that be possible. Just transplanted a few days ago into these 1,7l pot's. Since it is the first time i use the The Mars Hydro TS 1000 for flowering i think i might have given the plants too much light.

Leaves are fanning upwards and undergrowth is huge in flowering phase. Should i be worried about the upwards fan, should I trim on this point or just leave as is and just remove dead leaves?

Upper leaf
Although the general condition of the plant looks good, some upper leaves started to claw. I would like to get expert opinion on the cause and solution of this.
