Pritch....I think making the additions to secondary should be just fine...the ferment should re-establish. Just remember that this last leg, since it is mead, can take some time to finish out.
I would opt out of energizer/nutrient additions at this point. You may want to review the sticky on staggered nutrient additions, aka SNA.
I have a pumpkin chai mead clearing and it is going to be a good one. Best of luck to you!
