In general you ladies look ok but if you see those sign i wouldnt try to gamble. I would transplant gently to a bigger pot and add small amount of soil.lower ppm and ferts and check canopy temp to keep around 25c.

@BloodBath If everything else is on point then I would assume it's a Root problem Being too damp may have led to Bad Bacteria forming in the root zone. If this is the case I would reccomend an immediate treatment with H2O2 or something similiar as root rot (if that is indeed The issue) can kill the plant quickly if left untreated.

First your plant looks to be overwatered. Overwatered cannabis plants are droopy with leaves that curl down. As a result of overwatering, leaves often turn yellow or show other signs of nutrient deficiencies (especially when it comes to younger plants and seedlings!) Overwatering does not always mean you’ve been giving the plant too much water. It can also mean that you’ve been giving the plant water too often, or growing plants in a growing medium that holds onto water without enough air, or doesn’t have good drainage out the bottom. The best thing you can do for overwatered plants is give them time between waterings, and then start off watering slowly until things seem back to normal. Make sure that water is able to drain easily out the bottom of potted cannabis plants.
