Yellow leaves from veins

Nitrogen. At this stage in your grow, it's almost always nitrogen, although magnesium is possible if you start getting random brown spots too. Your feed should be somewhere around 300-400ppms right now. If it's much higher, you could have a lockout.

Moin, bei meiner Größen Pflanze fangen die Blätter an von außen gelb zu werden und braune Punkte zu bekommen. Ist das ein Zeichen von einer überdüngerung? Alle anderen Pflanzen haben dies nicht. Oder zu wenig?
