leaves feel dry

Hey there, it unfortunately is overwatering, you can tell from the puffy space between the veins of the leaves . That downward curling is due to some kind of water mold. Basically it's not your fault, happens all the time with the plastic pots. keep not overwatering, probably wait an extra 18 hours than you normally would, the main idea is to water just before lights on aswell, that will help just a bit. To fix the root zone issue , you need to break down problem roots with a chelation agent for example enzymes or humic acid, or even beneficial bacteria like bacilus subtilis or thuriengiensis . Just start adding either of those (not all three!) and the problem will stop spreading almost immediately and the plant should fully recover within ten days. Hope this helps ! 🚀
