Update
Everything goes well, flowering is going to final phase. Switched to 14/10, just for fun
Brewed another bacterial tea, used half of spoon of Bactobloom bacteria, half litre of tap water and couple spoons of sugar. Brewed that in aerated bottle on warm radiator for 3 days, till bad smell is gone and all bacterial activity is slowed down, because of that sugar being eaten. Got some brownish liquid with normal smell, used that for DWC instead of nutes while feeding. Seems that this way i could give my plant bacterial subproduct with chelated microelements, instead of letting bacteria to live in DWC, plus liquid silicone i use does not let them live in DWC normally anyway.
This is my experience and these are my thoughts, maybe im totally wrong, but it seems to work for me exactly this way.
Here are things i done for this period of time
19 02
Decided to change tea in dwc, just to refresh things and clean the tank, just to avoid any troubles, and to try another "tea" brewed from "branded" bacteria "Bactobloom". These are not for hydro and i decided to go with their subproducts, brewed separately from DWC, instead of letting them to make these subproducts straight in DWC.
Gave 9l of tap water 370ppm, and:
Cellmax Hydrobloom 30ml A+ 30ml B
Cellmax Superenzyme 30ml
GT Liquid silicone 5ml
Cellmax flower stimulator 20ml
AN Bud candy 20ml
Cellmax PK booster 13.5ml
Tea is about 1500ppm
20ml of custom tea, brewed from Bactobloom bacteria, TDS meter shows 720ppm, but that is organics and ppm thing means nothing here
22 02
Gave 1.5l of tap water and 150ml of custom tea, brewed from Bactobloom
Shower with 0.2ml of Plagron Sugar royal and 100ml of distilled water
TDS meter shows about 1300ppm now in DWC tea. So far so good, she seems to like this stuff much
And here goes my plant, it is day 52 now. She will be not ready in 60-65 days, but i think another couple of weeks she will be done, and judging by these white "meat loafs" on her, she will give me plenty of good smoke. She's starting to smell and getting sticky as hell. I'm not removing more leaves still, these are very compact and im rotating whole plant once a day, just to let light fall on her on different angle, for part of the day. You can see few burnt top leaf near the lights, these are due lights overdose, not nutes, This time i managed allmost good feed together with bio, small overdose were there, but i spotted that in time and fixed that easily.
On roots there clearly are some living stuff, but that is not getting worse and does not smell bad at all, so i'm continuing experiments with bio feed
That's still some new and pretty well working stuff for me :
