:smoking:-- sorry mate, got busy with harvest and such! .... good to hear it's halted,.... Hmm, yeah, that looks like N-tox' clawing there,.. what other sources of N are going in, like Ca-Mg (yours is fine at 1-0-0), amino supplements, etc.,.. "hidden" sources,... the deal is, N is taken up whether the plants needs it or not, so it's not unusual to see it accumulate to the point that the plant can't use or store any more,... a pain, because the TB is a 4 on N right? You might do well to get a PK product with no N,.. Kool Bloom liquid 0-10-10, Canna PK 13-14, something like that,... might be she grows through it, so watch for worsening,...
... hmm, upper leaves usually don't show mg defc first, lowers almost always,.. so this might be the start of something else, a micronutrient, Zn maybe, still a bit indistinct to call yet,.... soil pH OK, not near or over 7.0? Another good product to have on hand is a micronutrient supplement, like Earth Juice Microblast, and do foliar spraying,...nothing is faster for getting in, and with immobile nutes defc.'s, it's far far more effective,... If you want to go luxury/speed, use Optic Foliar'sTransport with the micronutes-
