The bottom of the fabric pot needs to be lifted off the base of the pan, moisture will stagnate if the pot is left pressed against the bottom pan with little to no airflow fabric pot should never sit in its own runoff. In normal circumstances growing outside this would not apply so much, grow tents can very easily have dead spots for air circulation depending on setup, you should look to have an extraction fan on a cycle timer to exhaust air and create negative pressure, your grow space should stay below 50rh, also remember the RH at the top of a grow can be drastically different at the bottom.
Leafs heavy and folded, overladen with water.
Ambient 63 is slowing photosynthesis to a grind, along with light a plant needs heat to excite the atoms within the chlorophyll that capture photons, the optimal temperature or leaf surface temperature (LST) for photosynthesis is 85-86, (Veg only) (flower stage 1 stay under 80) (stage 2 under 68).
Set ambient to grow space to 80 degrees ish lower your grow lights until the top of the canopy gets as close to 86 without going over, this will send photosynthesis into overdrive which in turn should accelerate water uptake, all things in perpetual harmony.
Much love good luck.
