Damaged leaves
I have a problem with one of the plants, the leaves are damaged and some of them had to be removed, the plant is growing too slow. I thought it is related to Cal/Mag but I've been adding it for a while since week 2 and the problem is not corrected

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?

Dark green leaves in meringue
Is my girl telling me that the flowering fertilizer is too nitrogen loaded? I´m using top bloom from top crop, feeding at 1.4-1.6 Ec, and since last week I started to follow the feed-water-water schedule. The NPK of this fertilizer is 4-8-8. Should I adjust the input EC?

Brown rust spots on oldest leaves
Brown rust spots on oldest biggest leaves with curling inward - the rest of the flower is fine, just some occasional small yellow spots. No sign of pests. Maintaining pH ~6.5 but have soft water. Suspect cal/mag deficiency or nitrogen toxicity. Thoughts?
