Let the soil dry out to almost the point it was when you filled the pot with dry soil at time of planting.
Try to water it before the leaves start to droop down.
Do this every time you water the plant and feed the plant, let the soil dry before watering and feeding to a point where it's almost as light as when it was planted, but before leaf wilt.
Be sure to TDS and PH your water before watering and feeding.
Most people have problems growing cannabis because they water too often and eventually end up drowning the plant.
Keep your lights close enough to the plant where the plant can make use of all the light is providing but not close enough to burn the leaves.
Provide plenty of fresh air to the plant by use of a fan, make sure the fan does not blow directly on the plant, have it hitting a side wall so that the plants leaves are fluttering slightly only.
That's not mold.
