First Fastbuds Run

I would say another 3-4 weeks.........a bit early to stop feeding imo. When there are 95-98% brown pistils, you will be entering the harvest window.

Even if you have increased cal/mag, results will take 2-3 weeks to show in the leaves. Just because you have been using cal/mag every water, does not mean that you have been using enough, especially if you were using powdered cal/mag, which takes a lot longer to become bio available to the plant. Liquid cal/mag will be easier for your plant to access, however, the damaged leaves will never recover, but it is all about stopping the problem from getting worse. Being this close to harvest, you might not see any real improvement before harvest day. Remember, what is showing in the leaves now, is a direct reflection of what was occurring in the root zone 2-3 weeks ago. Remember too, once the leaves are damaged, they stay damaged, the brown spots will not go away, no matter what you do. However, the spots will not affect your plant in any sort of negative way, they just look ugly.

By what you explain it seems like you could just be growing outside. If anything..it’s hurting them moving them back and forth to take inside. If it’s not getting cold at night there’s no reason to take them in. Also, if you have other plants that stay inside, if you did wind up getting a pest you could take the pests inside
