Light/heat stress most likely! I had a plant taco before because it was too close to the light. ✌️🏻💚🌿

I had this issue about week 4/5. I figured for me it was heat stress. What’s the humidity and it could also possibly light distance.

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!

Week 2: One of the plants still doesn't look good + other beginner questions :)
Second week and one of the plants has weird spots + leaves curled. Not sure what to do. Do I overwater? Is it some kind of disease or deficiency? No idea. Also, when should I start feeding the plants? And how much water do I need at this point? 😥

This girl is the only one in the growth tent (she is with other 3 strawberry cheesecake auto plants) with leaves curling up. The lamp to plant distance it´s at 80 cm, and the wind source its not hitting her directly. Could be overirrigation?

Upward curl
Hi Breeders, Elizabeth is growing well, but the bigger leaves are curling up at the edges. I already increased lamp hight and lowered to 18/6. Is it air humidity? Or too much water?

Nutrientburn?
I think one of the rootdiscs was very salty from the last grow. So that the plants have a little nutrientburn. The new growth is without any brown leaftips. The rinseout ph was about 6.3 and ec 0.6... can i do something more than rinse them with 10l pH-regulated water?
