So it took forever, but one cutting actually rooted the other day! The other went to 90% yellow and got some white hairy mold growing so I pulled it and there was some big, nasty, bubbly, tumor-looking growth on the bottom like it was preparing to grow roots but never did.

Here's the clone, doesn't look that great in the pic & it's so tiny but it's getting new growth now (3 more sets of leaves than in pic) and staying super compact. I'm guessing it'll veg a little before it autoflowers but only time will tell. If it does veg & grow branches, I will try to clone some more to keep the strain alive because the original is my best looking plant from the 5 AF seeds.
