No picture for this but I noticed today that several of the bigger fan leaves near the top was no longer as nice and green as before. Now it looks like the leaves are getting a rust like appearance. Is this something I should actually care about this late in?
I would need to see a picture but I think just about all your trichomes would be amber before its really to late to worry about it. I think all living things will get to a point where they dont take in food through the normal means anymore, (roots, mouth, etc.) and live out the last days with what ever they have in stores.
I think starving a plant by flushing it sort of forces them to finish.
