Unless they're blocking light to side shoots / bud sites you can leave it on and let it do some photosynthesis, if it's completely yellow (dead) you can remove it, you should be able to pull it off very easily if it's dead.
so you have a moisture meter,what does it read? keeping it moist is better then wet. like purplegunrack said get to know the heft of your pots dry and wet. also you should let em dry out before watering again,but don't let em wilt. then when you water em go slow let it soak in then add some more as this will allow the soil to absorb the water. if you do this properly when you see water just start to seep out from bottom stop watering. depending on humidity temperature and air flow this should do you well for couple days. hope this helps good luck and grow on
