The rule of thumb is to water as required, erring on the side of less is better. It sounds like the bags get a serious soaking. Do you check for moisture beneath the surface? Stick a finger or hand down as far as you can into the mix?
Sounds like a lot of food too. How often are you feeding?
And, growing indoors, your flowers might need a helping hand to pollinate themselves. Outside, insects can help, their fossicking triggering the internal pollination mechanism. The breeze can do the same thing. Without those options available indoors, you can give the flowers a flick with your fingers.
