I think counting days is useless, following breeder instructions I flushed once and finally there still were three weeks left 
. Breeders always talk about āoptimal conditionsā (wich is not my case) and state always less flowering days to attire attention.
I just look at the trichomes, when itās done, itās done (or add one more week 
), no need to read the āinstructions manualā ā¦
