Curious if anyone else has experienced leaves like this on Durban’s. I know I’ve seen leaves like this when temps get cool outdoors but all flower sugar leaves are turning. Watered regularity and fed well in my opinion, so I’m not sure what else it could be. Thanks in advance!

Dry leaves / dying.
Why is the leaves of the one "cola" drying like this? Looks really unhealthy, at first i panicked that it must be mold or something like that i have never tried before. But the bud seems fine. Is it under watering as i forgot to water for almost 72 hours? And if so, why only one.

Are my leaves getting burned?
Hi peeps, here's the thing.The "bottom" of my leaves started to look kind of like they're dry. The PH is perfect 5.6 for hydro, I worry that the super low humidity of around 30 has something to do with it. The temp doesn't get hotter than 27C, at night around 18.Water temp is 21C

Rust and a few claws on leaves, thick dark green leaves
Best way to easily solve a potassium problem, I think 🤔, also some leaves getting claws, it didn't get overwatered So it must be the soil which is too rich? It only happening with 1 out of 7 plants.

Few splotches, anything to be concerned about?
Thinking this is because of the too humid couple of nights i subjected the girls to, by mistake. One morning the leaves were dripping wet, and in the propagator the humidity was insane like 98%. Have since taken out of propagator and starting nutes on Saturday.

Mutant plant worth growing?
Anyone flowered a plant that shows a lot of leaf mutations? Was it worth growing or did they turn out runty? I have a plant that’s been showing mutations since the start and it’s working on it’s 6th node now. I almost want to kill it off to let the better plants get bigger.

Weird leaves
My little plant looks a bit sad, leaves are a bit deformed and have different color kind of spots, does someone know what the issue might be? I was thinking it’s from low temperature but I’m not sure. Thanks for any advice!

Start Flower...defoliation for Northern Light?
Northern light came into bloom this weekend. It was treated only with the LST technique. Fat Bananas grow. One is growing naturally. On the second, however, the topping technique was applied.Some advice? Better to remove some leaves? If so, which one?

Are these leaf changes normal?
This is first grow to make it this far. I am unsure if my leaves are just doing their thing; or if I have a problem. She is an auto-flower. I am on day 74 from sprout, day 35-ish from flower.

Cal Mag from LED too close?
Brown spots on upper leaves mostly. Light was at 14" from tops, Mars says 18"-24". Top leaves got light bleached too. Moved light to 22", recalibrated ph pen assuming it's cal mag, given 2 feedings @ 1tbsp cal mag/gallon. Any other possibilities? Not bugs, I scoped it.
