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.

Yellow leaves Hi there, I have a Skunk #1 Auto plant, about 7 weeks old, at the starting of the 7th week some leaves started to turn yellow. I read two options, that it is an N deficiency, the other option that it is normal as the buds absorb the N from the leaves. Any ideas?
