The older leaves keep yellowing and dying, Only the buds look ok but not a safe green. I gave nutrients, it's not absorbing.Zamnesia says it likes col

definitely a problem with PH or a lot of nutrients 🤷‍♂️🏽

The plant weirdly started stretching and it became 4x what it was in a week,this is why at first i tought the nutrients in the soil ended so i believed it was eating everything i gave her, and it was very well trained and bright colored before the stretching (which is also when i started feeding noticing the velocity). I believed the problem could be the temperature, it suffered 39°C and its a cold strain. Humidity is always in an acceptable VPD range, maybe a bit less for vegetative. Light isn't missing and it's some quality panels just kept dimmed to consume less and being able to keep the buds close as possible as i have a really tiny vertical space,but yet i should train some branches down a bit more because from 10cm it gets dangerous for the leaves, while 20cm looks perfect. I will try flushing to be sure it's not only the substrate having the right Ph. I don't feed like a monster, I prefer the less necessary possible. So if it would start eating again it wouldn't be enough to go in overfeeding, even tho i wouldn't like this happening now, im afraid this could lead to mold inside the buds getting too old and growing at different rates, It happened with a do si dos which did produce a lot of huge buds with very few cannabinoids, Terpenes and mold in the inside. Can the heat rot the roots? My only headache is that i had plants suffering the same conditions which had no issues growing.

A few points I could see: - environmental issues - check temp/rh, in and exhale air as well as moving air with fan and distance to light - check your ph - should be 6.5 on soil that plant can take up mobile and immobile nutrients - maybe flush them all to get neutral ph lvl again and then start feeding with proper ph level that they can recover faster check out my profile or leave me a DM if anything needed :)

Soil Ph is 7

Nutrient lockout most likely caused by improper PH in the soil.
