I’d like to tell you what I see, Doci.
The first thing and what should always be done when rooting is the buds in the media or other/water should always be knocked off. That’s step #2 for me. This is the order in which I prepare any cuttings:
- fresh cut at the bottom
- buds are knocked off with my knife
- two vertical scraping-cuts on each side of a bud scar are completed
- I dip in rooting hormone.
- the cutting is stuck in the media/water
- the cutting is misted immediately
Your Issai is unfurling leaves while under water. There’s no callus which means at this point there is no root formation, whatsoever.
Meader has none callus. That’s 100% rot. The only way to try and create callus is to cut the bottom off again. And, btw, the whole bottom inch plus is rotting. You’ll need to go up higher for a fresh cut.
Your Honeycrisp (apple? doesn’t matter for now) has callus but, had you prepared the cutting so you had wounds on the stem, you’d have been much better off and would have callus there too, most-likely
Here’s an easy tutorial on rooting for anyone:
