New Grower ph in dwc

[Bigbb]

Tea seems to be keeping the brown slime from thriving plants looking great roots are brown in colour but I think this is off the tea.should I keep adding this for rest of the grow.there seems to be a lot o brown bits of sludge come back to res when I pump it out of pots to adjust ph / ec is this normal when using this tea.
Fingers cross tho they are looking really healthy and green with some nice buds starting to develop

yes if your going to run dwc tea is easy.... also I would sugest reading all the pages of grow of seymore buds grows as he is a dwc master... and he doesnt use tea, but uses a "additive" which has a herd...
