feedings during lights out period?

hello,
we are about to start our "24-36hrs of darkness period before flower" and was wondering if we should continue to feed the plants? is it ok to feed when its lights out? thx!

If your doing hydro ... i dont think its a good idea to let it go 36 hrs without water.....

But wait for an expert to answer...

If hydro continue with PH'd water, if soil you can just go to dark and no longer need to feed. Hopefully you have flushed.
