Upward curling of leaves
One of my plants has started to have it's lower leaves curl upwards & started to go a yellow tint that's harder to see in my images. Yellow tint is starting higher up as well I think, but the curling is only on the low leaves. Is it nutrient defficiency, heat stress, wind stress?

Yellowish color at the tips and wrinkles
My plant has been yellowing for a day now, I think it is a deficiency of some nutrient but I don't know what it could be, I have thought about buying NPK. At the same time, there are also a couple of leaves that have slightly wrinkled the tip and have been half lowered.

1 plant going bright green
Not sure why the one plant is going bright green, would this be nutrient lockout or am I just under feeding the plant? I've been giving all 4 the same amount so I'm not sure as to why only the one is doing this

Brown spots and yellowing pictured above. My best guess is a Cal/Mag deficiency. Was feeding Botanicare Cal-Mag Plus at 1 ml/l up until ~2 weeks ago (friend has been watering while I was out of town). Before I feed her, any advice on what the problem is and how to correct it?

Lower leaves yellowing and curling down
Do anyone know what's wrong ? I was thinking they were getting to much light in the tent with my flowering autos... I'm quite sure it's not about watering

Look like Zinc and Calcium deficiency? Watering with 5.8/5.9pH, 2.06 EC (Runoff 5.8pH, 0.78 EC) Few leaves had small nutrient burn on the tips earlier this week. Nutrient burn appears to have tapered off.

Yellowing Leaves
I'm concerned my plant may be prematurely yellowing. I've added Cal-Mag to see if that would help with the yellowing of leaves, but the issue persists. Yellow leaves are moving progressively higher up the plant, but my other strain is not presenting same problem. (See Post)

PLEASE HELP! See former question as well.
Continue to see deficency or burn in leaves. I have fed her only ph water for 2 weeks and it continues. I asked for help before, everyone just tells me what they think is wrong and not the reasons why. If you have an answer it would be appreciated to know your reasoning. Thanks🤘
