There's almost a science to watering, but at least it's not rocket science. Grab an empty bucket the same size as the one your lady is in. Add some drainage rocks and fill with soil. Now lift the pot. When the pot your lady is in feels almost as light as the one you just set-up, it's time to water.
Another method is to stick your finger in up to the second nuckle. If there is damp soil under your finger nails, it's not yet time to water.

By drenching your plants every three days, you are not letting the bottom third of the soil get the fresh air they need, and thusly the roots will rot in the stagnant goo this causes.
Also, the more run-off you allow, the more you spend on nutes, additives, and time spent online asking why the ladies look ill.

Likely a sativa dominant hybrid. Tiz normal.

I'm in the desert, and speaking from experience, cannabis plants are more forgiving than most folks give 'em credit for. 86 isn't too bad, but a good fan is a real good idea regardless.
