    You got temps and RH% and pH, EC numbers? What nutrients are you using?

    I grow in soil so can't help, but plenty of hydro boffins here who can.

    Hope your baby(ies) turn around soon.
    Fight for your health.

    Cool, probably lower than 0.2 then. You're over feeding these I think mate, reduce that ec back down to 0.6. They'll pick up in a few days and clear up, better to under feed than over feed mate, some strains just eat very little food.

    Less is more, go for the 0.6 see how they look in a few days, then come back and we can decide where to go from there

    in hydro a ph of 6 locks out calcium really want it around 5.5 then let it drift up as it usually would
    in my opinion this is a ph problem that's causing a calcium deficiency quicker due to a low rH in veg

    ec 1 is a little high currently, they aren't leafy or well developed so might be a bit on the egar side of things
