Die gelben Blätter und roten Stängel könnten auf Phosphormangel oder einen Nährstoff-Lockout hinweisen. Ein Lockout blockiert auch oft andere Nährstoffe wie Magnesium, Calcium, Kalium und Stickstoff. Die gelben Blätter könnten auf einen Stickstoffmangel hindeuten, was in der Blütephase normal sein kann, aber zu früh deutet auf einen Mangel hin. Auch Magnesium und Kalium könnten beteiligt sein, wenn die Blätter blass oder fleckig werden. Da du schon CalMag gibst, könnte ein Lockout diese Nährstoffe blockieren. Dein EC-Wert ist im normalen Bereich, aber achte auf den pH-Wert (6,2–6,5) und den EC vom Runoff, um Salzansammlungen (eher unwahrscheinlich bei BioBizz) zu vermeiden. Wenn’s eng wird, einfach spülen und danach wieder langsam düngen.

Advise to flush or feed in Veg Does this is look like a nute burn, deficiency, or ph problem? The two plants that are growing a tad taller have had yellowing tips some curling downward. Don’t want to overreact and cause it to worsen, they’re looking healthy otherwise. Any advise whether to flush or feed?

Yellowing leaves Lower leaves are turning yellow, these seem to be one that are hidden a bit from sight, so possibly not getting enough light, but it seems to be spreading, and one of them has fallen off. Is this some form of nutrient difficiency, or something simipler?
