Foliar Feeding at night?

Just wondering if it's a good idea or not?

That is up to you if you foliar feed or not,i would do it at night.Doing it when the lights are on will cause burns.I would stop when the plants start to bud so you do not get bud mold.
I have never felt the need to do it,if you feed them properly it is not needed in my opinion.OPH
