I will wait for Spring to repot. It is better for the water to drain out during watering, don't let it sit on water. It will not like that. 68F is actually cool temps..so it will slow down in growth. So once a month watering indoors will be more than enough. You will have to treat this plant like a typical succulent growing indoors, less watering. As I have said, it is active at the the higher temps of 80's to 90's to triple digits.
I am thinking the soil is already too compacted so any water you put is just not swirling into the roots. You can try for now to gently poke holes on the soil, be careful of the roots ,so when you water the roots, it actually gets some water. But delay repotting.. Wait for the warmer months.
