Be careful when taking clones they're often a source of problems!!
A wetting agent is your best friend fighting bugs, when I fought them I seen the difference a wetting agent makes under the microscope.
Without a wetting agent the hairs on mites react with surface tension in water creating like a safety bubble, with a wetting agent as soon as water makes contact them it immediately covers them up drowning them.
I got rid of mites 100% with H202 or citric (I'd need to check) wetting and/ or H202 was actually for the eggs the wetting agent with just water kills them effectively ime.
Fwiw I dunked the whole plant down to the coco gave it 5min and repeated and that was pretty much it tbh, mites for me weren't a huge problem compared to frickin gnats lol.
