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.

Any idea what is causing this crisping on a few of my leaves? I am maybe seeing some slight curling/taco-ing on the upper leaves too? I think the PH might be a bit high in my water too, it's 7. I've ordered a filter and some PH Dwon, the PPM was only 250. Related?

Brown spots and yellow tips in flower, started around wk 8-9. Thanks!
My 10wk old Auto Trainwreck started showing brown spots and yellow tips @ wk 8-9 but even after up'ing Calmag to each water wk 8 (1tsp/gal) it's everywhere now. It's been 75-50% the whole time- deficiency in late flower? Again big THX to the community - for more than just this.

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

Weird looking seedlings? (uploaded vid)
My seedlings, especially Seedling 1, look kinda weird to me. Seedling 1 appears to have some weird yellow spots here and there and the leaves look cut? They just look really weird and not like normal cannabis leaves, both seedlings have their leaves going up at the corners.
