A pot that size will likely need daily watering. Especially with the lights and fan on 'em.

When you do water, does it absorb into the medium, or does it all come out of the bottom?

Once dry, peat-based mediums (potting soil) rejects moisture, so you'll have to re-wet it slowly. (a half-cup per minute, for example)

Cannabis prefers a wet-dry cycle, but overdry and habitually oversaturated will cause problems.
