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.

Browning leaves? Did a soil slurry and dropped the water from 6.8 to 6.2. Does that mean it’s locking out? How should I go about fixing this? In peat pearlite and worm castings. Added about 6 cups of lime to the 20 gallons of soil thought that should have helped the ph?

Clawing/Yellowing? (def not over watering)
Anyone want to take a guess at what's going on with the clawing/yellowing? Very highly doubt it's over watering. It's slowly been showing more signs of it the less I water and I'm pretty heavy on perlite. Also using the lower recommended amount on the nutes.

Help diagnose hydroponic plants! Too much light/heat? Nutrient issue?
The plant's leaves on the right are wilting and drying out, while the leaves on the left are spiking. Just did a nutrient/water change but it didn't help, and it looks like growth is being stunted on the right plant. Humidity has been around 45-55 rh and temp 70-80F

I had excess N at the beginning of flowering, I did a root wash and continued applying fertilizers regularly, today it looks like this. A lot of green smell but not from flowering, leaves with necrosis, I'm in the final stage of flowering and it's still vegetating with leaves in good condition!

Everything seems to be OK except one thing (week 3). I thought using the greenhouses at night made this, but it doesn't. When I check the plants early in the morning, their leaves are slightly curled upwards, just along the edges. As the hours go by the leaves flatten. Any clue?

Why my plant's leaves curl up like that? I think that there's an overwatering issue, but is there any way that my soil is not good?

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.
