How much & how often do you water? What are temps like where the plant is kept?

Can't tell what it is, but is the C&S soil quite organic? If so, it could be that those particles are decaying. I am just guessing, so see what others will say.

You may reconsider your potting mix: very little soil (perhaps 20-25%) and rest equal amounts of grit and sifted perlite. Maybe try with 1 plant and see if any difference.

I water about once a week. Flood with draining holes. It's on the window ledge with sun and shaded sun throughout the day.

I just took it out of the pot since I reported not too long ago. I'm thinking that I didn't do a great job washing off the soil it was originally in and it's been staying too moist (?)

when I repotted I used about 30-40 cactus soil that I got from Jade Garden Nursery. I think should be ok? It's their recipe mix... :/

i got a bag of what they called hbc gravel/stones is that ok? At a stone landscape place.

I think I'll repot with 20% C/S soil and rest hbc and just hbc as top dressing. Would that be ok?

TIA

If there was peat hardened around the roots, they may still not be getting enough water.

Why shaded sun? Succulents need as much light as possible - sunlight coming thru the windows is already bit weaker than it would outside, shading it may not be enough.

I do not know what hbc gravel is. But as long as it is good size, it should work. If too large, it doesn't really help. Here is grit I use:

Yes I agree about the sunlight. It gets afternoon sun til sundown. It's the best window so far in house, unless I move them to the kids rooms which I don't trust them not being curious. :P

Thanks for your reply and your suggestions. Much appreciated!

Looks like a beautiful day today. May just bring them outside;)

I think I might agree with Liz here, although Rina has some great points and suggestions.

Thank you. Yes that's what it looks like. I've repotted. Worried it'll take over the roots and then plant.

When you repotted, were they attached to the big rots or the plant? If feeder roots, they would be.

It was attached to the roots and the soil that it clumped with, but not the plant.

I would agree with feeder roots, but it seemed a bit more excessive than just feeder roots.

(Kinda like dandelion seeds..the fuzz part...)

Ok this is what I found out in extension the the link Liz gave me from the other post.

The other poster (sorry long name) found out her's could be fungal hyphae stings. I looked it up and more reading this is what I found.
