Your leaves are a bit thin and droopy. You might not be watering correctly or have a ph problem. Do you have a way to test ph and runoff water? I’d make sure 20% of the volume you put in is coming out

Looking good friend! Just grew out a jack here auto have a look. She’s a wonder mine wasn’t that high in THC but beautiful bud structure. I can see by the leaves you’re struggling can you get yourself a dehumidifier? A 600ml per day would be suffice. As for watering them. Instead of saturating the pot you can water lesser amounts more frequently. Just water until there is a small amount of run off this means that the soil won’t be as “saturated” as it would be if you put more water through. This causing the plant to start using the volume of water quicker reducing the overall moisture in the environment. Another good point is good ventilation. If you have a large amount of clean air moving through the growspace this can also help.
