Hello,

Never thought I'd ever day this but it seems something is going wrong for my crown of thorns.

I bought the plant back in Febuary and kept it in a wall pot right up against a South window. It did wonderfully there. I was then trying to revamp my Sad succulent Dish so I thought I could transfer the COT into the pot with my Jade, and burros tail to make it look nicer and to have all my succulents in one window. Did that in August I believe. It now resides in a South west facing window. It was doing fine for the first 2 months but now I'm starting to see what looks like sunburn on some of the leaves. Also the thing that has me concerned is that the majority of their leaves have turned yellow and crispy and have fallen off. Usually the lower ones. They're starting to look quite scraggly. Other leaves bend and curl than turn yellow and fall off.

They are kept in a an extremely fast draining mix and are watered now about maybe every 2-3 weeks. I wait untill the soil dries completely before I water again. Then I bring them into the sink for a complete soaking. The Jade and the burros tail share doing perfectly well yet the COT obviously doesn't like something.

I have some gravel I placed on top of the soil that I put there to stabilize the COTs while they rooted. Could that be doing anything? I've been meaning to remove it but I guess I got lazy.

Here's a pic
