I added a couple pics of what looks like rust spots on the leaves of only the tall plant in 7 gallon. I’ve given these two plants the exact same feeding so not sure what is causing it.

Brown spots on lowest leaves
Hallo Freunde! Ich habe an den untersten Blättern meiner Pflanzen, Verfärbungen auf der Blattoberseite entdeckt. 😲 Ich vermute das etwas Überdüngung die Ursache ist. Week 3 Day 19 Wenn jemand die genaue Ursache und wie ich es behebe, erklären könnte? Vielen Dank 😗 Cawabunga 💤

I already posted it, but it's better to see here and it continues to spread
This appeared after a strong storm, but it doesn't stop spreading..two guys told me it's from the wind, as I assumed, but with the fact that it's spreading further, I'm worried

Rusty brown spotting on upper fan leaves, too much Tiger Bloom or deficiency?
Hindu auto, week 11 started seeing rusty brown spotting on upper fan leaves. At this point I was only using tap water and 4 tsp/gal of tiger bloom. That is aggressive so I backed off to 1.5 tsp. I watered with cal mag 1 tsp just in case it was deficient. Ideas? Buds seem ok.
