    Default Dwc ph

    Hey all,

    Started my first grow in DWC now everywhere I have read that the optimum level for ph in DWC is 5.8 I had many many problems with it being this low such as cal mag issues and find it really likes being up around the 6.2 even 6.5 and they thrive ... does this seem strange ?

    yes sir , only when the very early signs of defficiency occurs , unless your are using led lights then its a must as it cause the plant to uptake alot of it for some strange unknown reason

    Lot of growers let it swing mate, 5.5-6.2

    Mate

    I'm running a grow and got the advice to run 5.2 to 5.9 folier feed the cal mag 2 weeks before switch and two weeks after and I've grown some monsters the idea was to keep the plant hungry and well hydrated. Res change once a week and I haven't had 1 issue.

    Just thought I would share

    Happy growing

    I grow in rdwc I let mine swing around in the 5.5-6.5 range.

    That way it absorbs a whole range at one point or another.

    However I default to 5.8-6 and let it swing either way.
