Should I foliar spray with a 1/2 tsp of Epsom salt? Also, when foliar feeding with Epsom salt do I need to drench the plant top and bottoms of leafs?

considering VPD your RH is fine imo, as long as you have good grow room airflow

how often are you watering?

Being in 1 gallon hard pots filled with coco... I’m only watering every 2-3 days right now as my pots are waterlogged not warranting daily waters
