Welcome to the forum Ryan. Hope you keep checking in while you're gone.
If you don't do anything it will definitely turn green. Probably deep dark green. This may be acceptable but keep the pH up. See comment below. First thing would be to get the equipment hooked up and functional so you can circulate. Next thing I would do is get the pump on a timer. If it's a 120 volt pump you can get a very decent Intermatic digital timer with battery backup at Home Depot for under $30. If it's a 240 volt pump then you're talking more $$ for a timer but still around $60 for the mechanical type I believe. If you can kick the water around for an hour a day or so that would help. Having someone come around every week or so to check the FC and pH would really help. To make it easier on this person stock up on several boxes of Borax and maybe a dozen big jugs of bleach. In any case it will take time to 'calibrate' what the pool wants to do in your absence. You don't want the pH to go acidic so before you leave bring it up to 8 or so. Some people may recommend using floaters and may have other ideas. The trees should be done dumping so there may be no concern about a skimmer basket filling and blocking. You may also want to put your filter on recirculate if you can so you don't need to be concerned about the pressure rising too high and requiring a backwash. You didn't say what kind of filter.
If you can come home periodically, every few weeks or so, that would be nice. These are some of my initial thoughts. Let's see what you and others think.
