I now know what I'm looking at for earlier intervention next time.

If you ever see little white spots or scar damage on the leaves, like pin pricks, grab a magnifier and look under the leaves for the mites and eggs. This is the easiest way to spot them early. Once they begin building webs, the infestation is bad.

Glad you were able to take care of it before terminal damage was reached.

Another point made is that I need to start wearing my glasses when checking them.

Glad you caught it when you did. How did they react to the H2O2? Were your plants hydrated before you sprayed them? What strength was your H2O2?

All plants were well hydrated. I applied it at 3% and really drowned them. I found a bit of mould after first application so second round I left the tent open for a couple of hrs with a bigger fan on them. Seems to be a lot of leaf damage and it also killed off the pistils. I'm seeing fresh growth on pheno 1 today.
While stripping leaves on Monday I snapped 2 branches on pheno 2 so hung them to dry.
Just did a quick dry on a small bud to see if it's OK. Got heaps of vapour and am still smashed 3 1/2 hours later. Impressive.

The H202 probably damaged the tissue near the open wounds caused by the Mites damage. It damages our tissue damage when disinfecting a wound, why wouldn't it damage the plants tissue damage as well. I always noticed the same thing when treating my plants damaged leaves with Dr. Zymes. Keep in mind that because they can't photosynthesize as well, they may not require/tolerate as much light. Keep an eye on them.

I'm glad to hear you had such a stellar first sample. What device did you vape with? I have the Onyx volcano. love it!

3% is a strong application rate.

As far as I can tell it says dilute 1 part 3% hydrogen peroxide with 4 parts water.

So 20ml of 3% hydrogen peroxide to every 80ml of water!

Hydrogen Peroxide is a bleach.

Yeah I'll be diluting a bit more next time. There seems to be a lot of differing opinions on this. Interested to see if these things survive it lol. Nuked!

I have sprayed heavily with hydrogen peroxide on Monday and Thursday. Not seeing any signs of webbing but the plants didn't like the treatment a great deal.View attachment 79259View attachment 79259View attachment 79259

Did you do the treatment while the lights were on or off. They used to sell h2o2 for plants going up to 11%-13% about 15 years ago (its what i used to use) and it was fine so i think your plants will be ok. You have to remember due to the mites they would of been pretty stressed allready so the treatment will take its toll on them but they should be fine, plants can go thorough much more in the great outdoors and survive. Tip: Its best to do any spraying onto the actual plant in lights off time so that the water droplets with the strong lighting ( especialy good led's) dont leave burn spots. Just keep them healthly a give them some extra tlc for a few days and i think you'll be fine. Ive seen plants in flower with over 50% (probably more) of the leaves all burnt to a crisp and the buds are growing fine so i wouldnt wory too much

I was looking at my outdoor plants yesterday and sitting on top was a lady beetle. They always have lots of bugs on them and no spider mites. I will be looking at introducing a few for the next grow.

I use a Mighty. So far every plant from Mr Nice has been better than anything I could buy off the street in my area.
