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.

Is the slight yellowing ad curling of these leaves ok or indicative of something?
Curling and yellowing of leaves in a few instances, both near the top and bottom of the plant, with no noticeable discoloration on the branches in between. I'm feeding it 1/4 strength Grow Big (2Cups) and 1/4 strength CalMag (1Cup) when I water every 3rd day. Ph runoff 6.8.

Nitrogen toxicity and tip burn
Smallest plant (1st pic) was showing nitrogen toxicity and I just fed distilled water at 6.3ph to try and help. Bigger plants had some tip burn and curling up. Thought this would help them. Any tips on how you would treat this please?

Tips of leaves turning
The tips of leaves are turning up a bit. I guess they are doing that because of high temperature, but could there be any other reason they are doing this?

Any ideas on my lower leaves cupping? I'm thinking a root issue from overwatering. I last watered 6/11 and this started showing on 6/13 and has progressed. Soil is still moist and fungus gnats popped out of nowhere this week as well. Have SNS 203 for next watering

Otherwise healthy leaf curling in on itself at top of plant
Anything to be concerned about? This is a plant that has had a history of yellowing leaves due to I think nutrient deficiency. New leaves are coming in light/dark green. Maybe caused by being too close to the lights? (It is my shortest plant with about 1 ft distance)

Any idea why my top leaves would be taco'ing at the edges? I keep my room about 72-73 degrees and am just using one CFL bulb (45w) that I keep at least 6 inches above the plant. And I keep a gentle fan or two on her most of the time to keep the air moving. Thanks.

What to do with crispy curly fan leaves that do have some resin on them?, I'm already on flushing.
Some fan leaves are starting to look a bit too crispy and curly, they do have some trichomes, I'm 3-4 days into flushing. I'm not sure if the dry matter can "contaminate" the buds somehow, and don't know if I should do something about it, I'm planning to get some "bubble hash"

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.

Yellowing, curling tips?
I'm in the middle of week seven and noticing significant yellowing, curling tips, especially on the top colas. Is this cause for concern and what could be causing? Feeding low-dose (1/4-1/2 tspn/gal) of dyna-gro bloom and the plant is growing in MG soil. I know, rookie mistake
