your plants like to dry out almost all the way between waterings. Make sure that moisture control mg. Doesnt keep roots to moist. Only water when soil is dry. You can tell when cointainer feel much lighter when you pick um up. Is your mg fertilizer npk rating 15-30-15? If so 1/4 strength every other watering. Inless there is fertilizer already in your mg soil. Then hold off atleast every 2-3 waterings. Gallon contianers at proper temps should only need watering once a week. But they will need to be transplanted into bigger containers when you are ready to flower.
