FAIL !!! - Pineapple Chunk DWC

* Monday: I wake up and get to my DWC, the plant look good but the white gunk is back in force ! My air-stone is covered in white gel and the roots too now. I did change my nutrients again and added some H2O2. I figured that this won't get rid of the white gel so I ordered some powdered beneficial bacteria (Bacillus amyloliquefaciens subsp. Plantarum souche D747), I should receive it this week and I pray that this will save my plant. * Wednesday: Some good and some bad news today ! The roots are being EATEN by that thing in my bucket :-| I see some little chunk falling in the bucket and lots of white stuff again. The good news is: I received the benies today ! I just changed my nutrient reservoir again, cleaned everything and included the benies in my bucket. * Thursday: lights turn on and I go check on the plant !!! It looks like the two top leaves are praying which make me think that it is recovering for good ! I checked on the reservoir and saw that some white stuff is forming on the air-stone again so I decided to add some more benies. Also there is a weird brown gunk on the roots now. I hope this is good stuff ! Lots of new white roots too. I think I need to start brewing a micro organism tea ! I read somewhere online that it gives good * Sunday: the bucket is full of foam so I change it again. The pH is, again, raising a lot. I think I need to change the bennies and use something intended for hydroponics, the stuff I am using isn't. I ordered some TNC Bactorr s13. I should get it early next week. Good news (?): I didn't see any white gunk when I changed the water. There is only some brown slime on the roots and the stone. I can see some little growth on the plant.
