Hey there Joyful , looks like they're doing well but they're going a bit slow right? That's because the nutrition they're getting is missing just a little something. Right now you're adding NPK and a chelation agent called top max, top max is humic acid which breaks down the nutrients and the minerals in the soil . But what i can see is some purple stems and shiny leafs. The shiny leafs is from too much N which in turn is from lack of cal mag which is used to regulate the nutrient uptake of the plant. purple stems is a tell tale sign indeed. It is absolutely worth it to add cal mag, or if you're not into spending dollars on cannabis products at least some epsom salt. Add either one of these at every watering , remember to pull up a bit on the NPK, and you should be totally fine as long as you keep the top max going. So to answer your question, it's hard to say when it's coming down but it should be way fatter before you harvest. Sometimes trichomes can look milky or white if you're at the wrong magnification, remember to go 40x minimum in magnification otherwise all the trichs look white actually. Anyways hope this helps ! 🚀
