    Are these White pistils?

    Hard to tell but usually pre-sex flowers show between the node and the stem not the node and the branch. sometimes really young leaves look thin and white which i think is the case here.

    Trust me i know the pain of changing i got 120gallon rez of RO so i use between 300 to 400 gallons of prefiltered water a week. but water is cheap and why decrease your yield to penny pinch. the reason we grow dwc is because we get to submerge the plant in the perfect mixture of nutes at all...

    Rhino skin vs Botanicare silica blast. (need a hort person)

    LOL Armor SI is trash...10% silica dioxide. If you are buying silica in a liquid form you are getting duped.

    Droopy green leaves, purple stems.

    I usually water when the pots are light, the first inch or so is completely dry but below that is moist but not wet. Is this too soon? i will transplant to bigger pots and see if that helps keep the from drying out as quick. Maybe they were drying out too often and then i over ferted.
