For your first grow you did an excellent job bro, congratulations... Your girls look very close to being done.. What strain are they?and how many days did the breeder say they will take to be ripe? All your leaves look healthy still even at the bottom where they will start to die at the end so...
Hey UB, I aint no botanical geniuss, not by a long shot but I thought the value of "flushing" was to help eliminate salt build up around the roots... And at the end of the grow a flush would help get ferts out of the bud..Is this not the case?
Have you ever flushed in the 4 weeks ?... Or try a foliar spray using some epsome salt, 1 tsp per gallon. When you water, only water when they are completely dry, wait till they start to droop a little.... Peace
