smoke24answered grow question 4 years ago Are you waiting until the top inch of soil is completely dry before watering? Thats a big pot, and a plant that size is going to take a good 5-7 days to use up all the water that pot can hold. If they don't get to dry out between waterings, it make it difficult for the roots to get oxygen. The other thing is to check the ph of the soil , should be 6.5-6.8. Happy growing.
