Blue Dream SCRoG + Undercurrent DWC + CO2

I had no idea that peroxide could cause such a problem.

Me neither, and the thing is I didn't put all that much in there. I guess I underestimated the power of 29% H2O2. I can't blame the H2O2 entirely as the dirt and muck may have played a role too. Either way, beware of putting too much H2O2 in your hydro systems!

Berkman; How much was too much ?
Thanks.
 
Here are some shots from 2 days ago and today, you can see that they haven't fully recovered yet but are on their way. I am guessing I will have to add another week onto the flowering schedule to account for this fuck up.

I put about a cup or cup and a half of 29% H2O2 into 15 gallons of water.

I did some math and I put in about 5 times too much H2O2 if I were regularly running H2O2 instead of compost tea. For high strength cleaning, which is what I intended to do, I put in twice as much as I should have and the plants should have been outside the system during this flush. I found that too concentrated an H2O2 solution will kill ANY LIVING ORGANISM and this includes roots and the plants that they support. Lesson learned, I won't be doing that again.
 
I still have another issue to deal with; the cause of the dirt buildup that started this whole fiasco. My first thoughts are that there is something wrong with an ingredient in the compost tea OR there is a reaction between H&G Amino Treatment and the TEA. I got this nasty buildup when I first transplanted these plants into the undercurrent system and I was using full strength Amino Treatment and TEA. I had since run out of Amino Treatment and just got it again last weekend and that's when I think this recent dirt buildup started. Right now in the reservoir I have a light dose of Amino Treatment and no TEA at all. I just put some Orca in there for the time being until I can figure out the root cause to this issue.

Any ideas or thoughts?

I wish I had some input for ya bro...I agree that there might be some sort of reaction and you might want to go back to the formula you used last grow, unless you figure out what it is.

I checked my last grow journal (actual journal that I keep, not a thread) and I am doing the same thing I was doing last run with the exception of lower PPM because this strain likes less. I suspect there is an ingredient in the TEA that is causing this build up.

Did you make the tea or buy if from a hydro-store or something?

I make it and the only difference that I know of right now is that the humisoil is a different brand. Maybe it's a bad batch or has something in it that causes a reaction with something else in my hydro system.

I dont know anything about teas. I get raw humus from a dirt and rock yard and use it for my outdoor veggies in the spring though.

Do you strain the mix through pantyhose or a sock or something?
 
The plants are looking much better so I decided they could use a nice foliar feeding. I also added a little more base nutes and brought the additives up to 100%.
 
I also noticed you don't have a lid on your control bucket? I hope it is not like that all of the time? If so, you may just be getting a form of algae building up in your system! Light and water don't mix.

It's not usually like that, I was taking these pictures while working on the system. Thx for the heads up though.
