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.

Nutrition deficiency or nute solution on leaves during watering?Hi Growmies,during my monitoring routine I found some brown spots on the leaves. Not many but on some leaves the brown spots have become transparent and I can see through the leaves. Any ideas what could have caused the brown spots? Perhaps not enough CalMag? Rest looks healthy.

Weed doctors to the rescueDay 44, fb auto, my happy girl developed those dark spots at the top... Is this a Calmag deficiency? Although I'm giving her calmag every feeding. I think there are also first burnt tips. I'm about to water her tonight, what should or should not give her? Thanks for your inputs🙏
