Get a pH tester and a soil test kit and see if anythings too far off. I can't tell what mix you're even using... wtf is a fertilized pre mix? If its generic potting soil, that could be an issue, it's usually too heavy and the plant can react like it's overwatered even if you let the soil dry out between waterings. But if it's a potting mix, the pH is prolly ok...
the soil recommended to me by a famous growshop (specifically for cannabis plants) in Holland, so I don't think that it is the soil at all since loads of people use the same one and never complained.
