Trying to Fix This Auto Flowering Rust Spot Issue - Potassium Deficiency I Think - Join Me

I have had some rust colotncoming onto the leaves slowly. it starts as a discolored green then slowly becomes a yellow rust. it's not too bad yet but DEFINATELY needs addressed. I think it is Potassium deficiency, as that can cause issue with the Uptake of Magnesium and Calcium, both of which are needed for a healthy leaf structure and plant structure. I know I have a soil root system. Discussing nutrient issues. advoc8 always meduc8 Daily. $bloodshotkoala
