First flowering week has started.
I feel stupid because in my case, at least in a similar setup to mine, you can't use any organic nutrients. Everything goes to hell, the pH goes to hell, etc. I wasted years on this. In ress, the water cleared up just as clear when I cut out all organic nutrients and everything stabilized. I think this should be talked about more and emphasized to new dwc breeders like me.
I had also calmag defiency but it should be ok now.
