Week 19 and I am still holding out hope for a fully ripe harvest. I am beginning to see more white trichomes, but still plenty of crystal. I would be okay harvesting now. Surely the weed is pretty decent. But now that I am seeing color for the first time, I would like to see some red. The finishing time is tremendous, but if the weed is as good as I think it is - I am going to reveg. If successful I will use a different organic flower food for flowering, first using seaweed for the reveg. And start a second plant, of course. I am on a 10 hour photoperiod now so the 2nd plant is a no-go. I plan to top the second plant, while waiting to see if the reveg takes.
