many problems with the leaves
the leaves have been turning yellow and falling faster and faster, especially those below; the upper ones curl and become burnt with dots and turn yellow should I try to put the lamp higher? (I haven't given fertilizers for a week)

Leaf discoloration and deformation.
Getting a weird discoloration that I can't match to anything I have seen. Even shows on some newer growth. Leaves deform a bit with it as well. She was flushed to 6.5 PH runoff 5 days ago. Just fed today with 1/2 str FF trio nutes and noticed the abundance of discolored leaves.

Twisted, yellow/brown tips.
Hi, My plant has shown signs of a nutrient excess throughout its complete cycle. It keeps to the tips of younger the leaves that have a tiny twist in the end. I don't think it's the light as it also affects leaves in the lower canopy. I keep on flushing but nothing changes.

Sudden Leaf Yellowing – Lighting Issue or Something Else?
Hello! Yesterday, I noticed the top leaves turning slightly yellow, but today it looks dramatic. Check the pictures—leaves are yellowing and drying out rapidly. It’s only affecting the central leaves, so I suspect a lighting issue, but I’d like to confirm before taking action.

Pale automatic seedlings
I've transplanted all seedlings (automatics) into water reservoirs. I've read that they need 1/8 then 1/4 etc. of normal nutrient dosage. Im using green house feeding nutrients for the first time. I've put 1/8 which seemed very little nutrients and 2 days later they look pale.

Curling leaves - heat stress?
Some of the leaves are curling. Sits next to another indica that doesn’t seem to be affected. Temps here in Arizona have been 100-110 for weeks. I presume this is heat stress but would 💗 2nd opinion. She’s in the most protected area of the garden, so probably can’t fix this.

Leaves curling on sides
Okay so the leaves are acting weird and kinda curling in on the sides. Like it's heat issue. I think maybe to strong LEDs. Idk. It's only 79°f Light (ESv300) is on lowest setting @32in away. Fed GH flora trio. Only 237ppm. The leaves are also yellowing between veins.

Tacoing leaves but temps around 24 highest and light is fine to 60cm from top and on 25%
Looks like its not heat or light stress, what could be wrong with her? She had one time in veg more than 36 hours light and now she cant get back to beeing normal. she is living in 11l shoes, had 2ml per L even if she is a 11w old clone. Maybe i need more food?
