Morning Zack, have you been checking your ph? In an out, ? What kind of lights are you using ? How do you water your plants ?
A good dose of nutrients wouldn't hurt, if not that a shot of molasses.
Pretty ,nice ,buds forming.

Morning Sgrl, a little early for that kind of yellowing, even for an auto.,,but anytime you want to comment, you go right ahead, you probably know as much as anyone else, so don't let that stop you. You got a grow going Sqrl on here ? If you do I bet your plants are looking nice.
