FAIL !!! - Pineapple Chunk DWC

ParanoidGuy Monday morning: I seed the tap root coming out of the cube. Moving to my homemade DWC system.

ParanoidGuy Start to grow small roots outside of the pebble container.

ParanoidGuy * Monday: The roots are finally reaching the nutrient solution. I can see that the plant start to grow much faster now :). I will try to take more pictures this week to show you. I decided to add a little more nutrients compared to last week. Also I noticed something great with my new pH reducer: it doesn't change the solutions EC ! * Wednesday: As you can see on the picture I took on Monday, the lower leaves don't look that great. Today it's worse, they are completely dry and dying. I will cut them off. I saw a brow root in the reservoir, I decided to cut it. Also I cleaned the bucket with some soap and the air stone because it was covered with some sort of white gel. Now I am crossing my finger and hope that the plant will survive ! * Friday: Bad news again... I think the plant is infected with "cyanobacteria" (source: https://www.rollitup.org/t/help-white-gel-on-roots.346004/). I have all the symptoms described in the thread: the solution is turning all white because there is some kind of white gel floating in the bucket and it is spreading like crazy ! Plus the pH is skyrocketing from 5.8 to 10 in one night... Good point though: The plant looks healthier and it is still growing ! I will try to give the roots a bath of strong h2o2 solution and disinfect the bucket again. * Sunday: I think the disease stopped spreading. I see that the leaves don't die anymore, new growth is showing up and new roots are popping in the reservoir. I decided to top the plant Saturday because it was recovering.

ParanoidGuy * 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.
