Hello, I posted this question originally on Reddit's succulent page but never got a response. I brought home two kalanchoe tomentosa / panda plants from IKEA on Sunday 2/11 and repotted them on Wednesday 2/14. Removed as much of the old soil as gently as I could with a chopstick and then moved the two into a larger pot with a 50/50 mix of fresh MiracleGro cactus soil and perlite. This is where the huge mistake comes in. I did not know that succulents should be left alone for at least a week after repotting. I soaked them for a minute or two and then did some googling on the matter before yanking the pot out of the water. The soil is definitely damp now though and I think they're still in shock from bringing them home last Sunday and all the other changes to their environment. Their leaves have started to spread outward and right before repotting, I did notice on one of the pandas that one leaf in particular was limp and brighter green than the others. They have been sitting about 4-6 inches below a Philips CFL bulb with 1600 lumens and 6500 K in the color temperature spectrum since Wednesday, which I've been trying to leave on for about 8 hours since. They don't seem to be getting any worse, but I would like for their leaves to perk back up!
My questions are:
1. Should I repot them into new soil that I haven't (stupidly) watered, and would it be safe to do so without shocking them further or outright killing them?
2. Is the terracotta I placed them in too large? I read succulents don't really enjoy too much space in their pots, and these guys did have what seemed like shorter roots when I pulled them out of their plastic cups.
3. Is 8 hours of light per day adequate for kalanchoe tomentosa, should I increase or decrease the time? Move the bulb further away or closer to the plants? Are they more sensitive to light after repotting?
I would be extraordinarily grateful to anyone who can provide any answers or guidance.
