Ok so a few of my other plants that are not as far along have the same problems. The leaves around/in the buds are turning brown. The pistils are not even brown yet and I know its not time to harvest. What could be causing these problems. I have been giving it bloom buster and molasses every other feeding. their is no mold issue and they are under a 250 hps. Any expert out their know what is happening so late into flowering.
