Looks like heat stress ,if your light has a dimmer try turning it down some. If no dimmer then raise the light if possible.

Weird Leaf Problem
New leaves show strange twisting/curling. Humidity ~50%, temps 28-21°C (D-N). Did LST last week—could twisting be due to reorienting to light? Using All-Mix soil, Bio Grow, Calmag. Water left 24h, not pH'd. Some leaf holes caused by me. Flipping soon—help resolve this issue!

First time growing/Need help in late flower
Over the last 9 days my plant has gone from happy and healthy to sugar leaves pointing straight up near the top of plant and drying and curling up on the lower levels. Is this from too much light or did I over feed late in flower? First grow/ no diary. Can I save or do I chop?

Leaf Troubles: Nutrient Overload or Calcium/Magnesium Deficiency?
What’s happening with these leaves? The tips are curling up, and the DLI is below 45. I’m unsure if I’m overfeeding nutrients or if there’s a calcium and magnesium deficiency. What do you think the issue is? Please help me, I need to feed in a few hours.

Slight lightburn?
First pair leaves on left plant turn slightly lighter, first sign of yellowing a bit. Also I think they are a bit in a V/praying shape. 2 full weeks old under 75% of 200W leds about +-45cm. Should I dim them a bit more/hang higher? Other suggestions maybe?

2 autos with crispy feeling sad looking leaves, how can I help them? (more info in diary pl & crit)
2 of my autos have been growing leaves that feel crispy and look deformed. I have been watering when the top 5 cm of the soil dries, but I fear maybe I fed them too much nutrients. The temp has also been on the high side (30C 80F). What could be wrong and what can I do for them?

This margin curl appears to have spread from one plant to 2 of the other 3. So I assumed not pH, not lockout, not nutrient based. Roots all great. I've culled the 3 and there is 1 survivor doing well but what was this? In the diary I mention using Temprid FX, Neem, Spinosad.
