if youre in soil then don't water until runoff. its not needed like with coco or synthetics.
at this age i would water with 4 cups every other day.
then once the soil starts to dry out daily
start watering with 8 cups every other day
once that dries out daily then do 12 cups and you probably wont need to do more than that
normally 8 cups every other day is where youll stay
