hey there auto floo , you have root problems , this you can see from the downwards drooping and yellowing of the leafs. Basically what happened is there is a bit of mold from overwatering. The overwatering you can see from wrinkles between the veins of the leafs. What you want to do to fix the issue is not overwater anymore, then fix the problem roots. To fix the problem roots remove the "top max" which is creating stickiness in the soil and giving fuel to the wrong kind of bacteria at the root zone. Then increase the bio heaven probably to 2mL / L . the bio heaven will stabilise the whole thing. Hope this help ! 🚀
