Can I put rooting hormone on clones after they've been in cloner for weeks?

I did clones exactly 2 weeks ago today and normally by now they have baby roots forming but this round there's nothing on any of the 20 I took. I'm using an aero ez-cloner so I could still put rooting hormone on

Kinda like chicken soup, it couldn’t hurt!

Using a few drops of bleach per gallon really helps to keep nasties away. I put one drop unscented 5% bleach in every 4th day in my 1 gallon cloner.

Cheers!

From everything I've read, rooting hormone doesn't work like that, it won't be effective because the concentration of it making contact with the plant will not be high enough.

I have done it with rooting powder, I just dipped the stem in the powder again and gave it a minute or two before turning the cloner back on. I've also pulled the neoprene plug and let the cutting soak in a rooting powder slurry for a couple minutes before returning it to the cloner. Both methods have worked for me in a clone king

Has their callus formed? Are the stems still firm? At 20 days I normally find a few have given up and their stems are soft (starting to rot). Do you scrape your cuttings to expose the Cambrian layer?

I run KLN in an aerocloner.
