I note that the feed was said to be "1:1".
50/50 syrup (by weight) is given as fuel for immediate use, typically to provide fuel for wax-making when drawing new brood comb.
If you have a fully-drawn brood box AND less than a couple of frames of stores AND no crop super(s) on, then a little bit of stronger syrup (for storing) might be appropriate.
However, in most of the country it seems that there is nectar available to the bees, and feeding should not be needed now.
The concern for those that have been feeding is that there may not be enough empty comb in the brood box for the Q to lay in. Restricting her laying with excess stores promotes swarming.
In summer, the brood box is for (the clue is in the name) brood ... !
(Not food.)
