Tiny mold spots on clones

This is my first time cloning in an enclosed humidity dome. I've made many many clones previously, but always by DIY aero cloner based on designs I saw on StinkBud's thread or in soil in Solo cups. I figured the humidity might cause a mold problem, but everything seemed to be doing okay. I noticed the first roots 6 days ago, when the cuttings were 11 days old. 3 days ago I started taking the dome off several times per day for ten minutes at a time to give them a little dry air time. Now the cuttings are 17 days old, and I see roots on about 20 out of the 30 cuttings.

I noticed 5 or 6 of them had one or two lower leaves each that were shriveling up and turning brown. I decided to trim those off. When I was closely inspecting the spot where I was trimming, I noticed some teeny tiny, fuzzy mold spots on the dead tissue. I trimmed off all the moldiness, but I'm super paranoid about infecting any other part of the grow. I've never had mold problems before, but I've heard plenty of horror stories. I've always neemed my plants during veg as preventative maintenance, and I think that helps with mold/mildew in addition to bugs. Anyway, I've never had a mold issue before.

If anyone has a protocol for sanitizing clones for contaminates like mold, please comment. If I'm just being too paranoid, and these aren't anything to be too concerned about, please also let me know.

Much appreciated. Peace!





In the pic below. You can se two of the leaves that had mold spots at top-center and top-left

H202 will usually get rid of mold. those things should have been hardened off a long time ago. Leave the dome off

Can you suggest a dilution of H2O2 to use?

Thanks for the tips!

Yeah 3% will work , up to about 10%

I lowered the temp on the heating pad and have left the dome off since the last post. Almost all of them are starting to show roots. I made a very light nutrient mix and made sure the plugs are plenty moist. They stayed perky for over 24 hrs now, so I think they won't get the dome any more. I can tell they are starting to veg. The growth shoots are starting to grow a little. I checked them thoroughly, and I don't see any signs of any fuzz or anything else wrong, so I hope they're in the clear. I'll be closely monitoring.
