что с листьями?

I think low RH with high temp. According to the VPD chart: RH 44% with 18C, or RH 70-75% with 27C is good.

Hi plugged in , you have two problems one from before one from after your flush . So your plant has some small root problems from the temperature , you can see from the taco-big of the leafs. Now you have more problems from the overwatering. If you can reduce your temperature to 24C and follow a strict wet dry cycle then the plant should recover. If the problem persist you need to add additive like enzyme , h2o2, humic acid or beneficial bacteria to fix it. hope this helps ! 🚀
