Yo Ho buzz4fun,
First and foremost allow us to extend a hearty welcome to you. Do be sure to peruse the site rules, they are few and easy to get along with.
Bring a good sense of the Ha-Ha with you, and we will spark one in your honor.:smoke1:
Now as to your plant, I would recommend a do over. Red ants are veg eaters, and that is most likely one of your problems.
Red ants won't usually kill the plant as that would do away with a food source instead they will slowly harvest from the plant as the plant fights to heal and grow. My experience reminds me that red ants also do not make their homes in rich loamy soil that your plant would do well in, (unless they are the tiny little stinging type), instead they prefer to dig and tunnel in a hard packed clay/sandy soil, or at the very least a seriously dry soil. Their tunneling will destroy roots and channel away water also.
Forget the idea that your going to suddenly get buds over night. As to watering, all you need to do is dig down a foot away from your plant, dig down at least 4 or 5 inches and if the soil has some moisture to it then leave the watering alone for a longer period of time. But as I said a do over would be best so you start out with a healthy plant. It is certainly late in the season and your daylight hours, and evening temps are not going to be enough to get you re-vegged and then flowered. Like I said a do over might bring you the happiness that your looking for. Can you do some growing indoors ?
A stealth growbox can be built pretty easy if you can't afford much, and we can certainly advise you well in this regard.
smoke in peace
