Having a few problems with some Brainstorm plants - looks like a ph lock out of salts but even flushing isnt helping i'm running everything else at 5.8 - 6.0 which is normally fine is B/S meant to be run at a very low/high pH food level - i've searched everywhere for info but can't find anything thanks
that's odd. by those numbers i'm assuming you grow hydro? my experience with multiple strains is more of a sensitivity or need for feeding rather than different PH levels. maybe try lowering the PPM for that 1 strain if possible. good luck
thanks man - yeah , I have 2 in soil and 2 in hydro - the hydro ones are not looking great - I'm flushing them as we speak at first they showed sign of needing nutes, then over nuting, then pH lock out, then more yellowing and necrosis - doing my head in!
