Feeding can be done as needed. Beware of potential robbing. As long as your not pulling honey off apigard treatment is no reason to stop feeding.
Some folks feed MegaBee patties to induce laying. ( Pollen patties). Bee Pro is another brand. Not a bad idea unless it's really cold where you are.
My mentor has suggested I continue feeding due to the severe drought. I am praying my girls make it. I am now useing 2>1 ratio. My queen stopped laying for a bit so don't be too worried..Bees are far smarter than us...they know what to do. Best to leave them alone unless you feel there's a problem.
