Shouldn't go by "days gone by", bro. You'll need to feel the soil with your fingertip, go a few inches down. If she still feels damp, don't water... It's very easy to tell with that method (opinion). Another way, is to feel how heavy your pot is right after watering, and right before. Soon or later you'll know when to water by the weight of your growing pot. Best of luck to ya!
And also, I've noticed that right after watering, many leaves will "droop". So if your experiencing this right after watering. That might be why
