One new top leaf is wrinkled too, so I would go with bad watering regime and overwatering . Pots has to be light before watering them again. All the Best !

greyish leaftips and dieing branches after topping
the highest branches died after topping. It looks to me like they had the same symptoms like some new upper branches are developing now. It looks very dark & feels soft Temps were 17-19°C & Humidity was 90%+ Water should be PH5.9, think ph reader might be wrong and ph is too low?

Weed doctors to the rescue
Day 44, fb auto, my happy girl developed those dark spots at the top... Is this a Calmag deficiency? Although I'm giving her calmag every feeding. I think there are also first burnt tips. I'm about to water her tonight, what should or should not give her? Thanks for your inputs🙏

Black spots?
Is this a deficiency, nutrient burn, or disease, growing in MG soil, recovering from overwatering as well.

The problem in plants when I supplying CO2
Hello! After adding CO2, I noticed problems on the leaves of my plants. Grow in coco+perlite, water with 1100ppm solution, 1000ppm co2 in air. Drain from the right 1400ppm and 1800 from the right. Is it related to co2 and irrigation system?

Nutrient Burn, Leaf Septoria, Nutrient Deficiency? Or something else?
I have been having issues with the Purple Haze. I've tried adjusting the Temperatures, adding additional Cal-Mag, changing lumen intensity etc. I believe this may be nutrient burn? Added an old image of leaf before mainlining, the plant is 1 week old after mainlining was done.

Cold or hot extraction for antioxidants?
What preserves anthocyanins in our cannabis leaves better? If we want the antioxidant properties so we can use them for our benefit, which is better? Cold gentle extraction or use of heat? A traditional african practice centuries old makes tea from leaves to treat certain illness

Brown/Grey spots on the leaves
Hey, I hope this is my last question for this grow :P I've noticed some brown/grey spots on the yellowing leaves, what could they be, deficiencies or sunburn? I'm still feeding the plant with nutes, but the next watering will be a flush, so I didn't expect discoloring before that
