So I have 3 plants going in a 3x3. We are in our 4th week of flower and one of the plants (XXX#15 by ethos genetics) is showing some weird color on her main cola. The bud has turned yellow/white and is a different color on half of the flower. Any suggestions or insight would be greatly appreciated. This isn't my first grow just my first time seeing this.
