I Asked because my pistils never did turn orange or red a month or two, after they opened. The reason I said 70%-75% , the article mentioned something like the THC changes to another chemical that lowers the grade of the harvestAnd make sure no more piltils turn color at once. My harvest was lower THC because I did'nt get the males out quick enough (stupid me), it kind of pissed me off. The next grow is already germinating, planted tomorrow ( white widow seed I picked up). Thank you for thhe help. I may call again about a new problem.
