    6.0 to 6.3pH for vegging in hydro. DWC

    For pathogens in the water use SM90.

    It's normal for pH to swing and you got to keep on it, it always changes. Plants eat and drink the water, that is why it swings.

    If it is really out of control you might have bacteria or pathogens.

    Use H202 and SM90 combination. Read about thier use and how it fits your situation. Make sure your water is de chlorinated.

    Also just in case make sure the water level below the net pots is around 2 inches give or take.

    Bleach, H2O2 & Sulfer are good disinfectants of hydroponic equipment. I use sulfer to disinfect my wine buckets. If I didn't I would get bacteria in the fermentation process and blooms would appear.

    they look hungry. feed them.

    .4 EC is nothing for a plant that size. They are eating that in 2 days max, which is why your ph shoots up quick. Feed them 1.2 EC
