Looking ok so far.
Any way to get a humidity and a temp reading? How are you venting the heat out of the top of the tub? In a set-up like that I'd be afraid of just pushing the hot air around and around and around, instead of out.
Overheat, overfert and overwater are killers.
Do not let the soil stay 'soggy'. If top couple of inches of soil is DRY, likely, it's time to water. Better a bit dry, than a bit drowned.
Some plants need constant and plentiful water available to the roots. (mangrove...) Some plants need the soil to be dry, or root rot will quickly develop. (cactus...)
Cannabis is somewhat in the middle but leaning more tword the cactus side.
