Firstly, congrats on your success so far.... way to go!!
Secondly, is there a disconnect between what you're telling SP you're burning and what you're actually burning?
Do you use a HRM?
If you're finding success at 1400 and don't see signs of under eating based on your activity then stick with it.
If you're experiencing all around tiredness/sluggishness, are unfocused or can't perform you're fitness activities like you used to - then it's under eating or overtraining.
If so, then you need to either up the calories to the SP range or scale down the activity and give yourself rest days.
You also want to make sure 'your' success rate is reasonable for how much you really need to lose. Are you trying to lose too much too fast staying at 1400 cal? Are you going at a rate of .5-1lb week loss?
