Last week of flowering... getting ready for the harvest. This week was all water no nutrients, probably will cut in 3 days.
Not much to add, this is my first time growing I'm proud of the result :)
I would say you have at least a week most likely two though. I would invest is a little Carson microscope from Amazon. The blue one work great and is around 10-15usd. That is the only real way to be sure. Looking good and happy growing!!!
