you should foliar 1-2 hour before light get on or after they get off.. you shoudnt foliar when light are on you will burn your leaf as a lens would :O.. but i seriously recommend before light get on you wont have high humidity at night temp..

Of course the feeding prior to lights on is a big no no if in flower...and if in veg running 24/7 lighting, it's impossible...
Dont get why some foliar feed, but I guess if your plants require it to grow then just mist them whenever...wont matter if they're in veg since they will always be exposed to light and most likely will experience light burn. If in flower, foliar feeding is a bad idea due to increased chances of bud-rot/mold.

I dont foliar feed personally, However if your going to, I suggest hanging some compact floresent bulbs throughout the canopy and shut the hid lights off turn the floro's on and foliar feed once they dry just kick the floro's off and kick the hid back on...
Never foliar after week 3 of flower IMHO, If you use the floro method you wont experience any burn, Least not from light...

It is fantastic if your plants are seriously lacking water, nutes, etc... but if you keep the root zone/soil happy and dialed in, it does nothing but waste em (IMO).

Foliar feeding seems to be one of the easiest ways of increasing yield, growth speed, and quality in a well vented space, with or without elevated CO2 levels as leaves are up to eight times more efficient than roots in absorbing nutrients. Just prepare a tea of worm castings, fish emulsion, bat guano, or most any other plant food right for the job and feed in vegetative and early flowering stages. It is not recommended for late flowering, or you will be eating the sprayed-on material later. Stop foliar feeding 2-3 weeks before harvesting. Wash off the leaves with straight water every week to prevent clogging the stomata of the leaves. Feed daily or every other day.
Best times of day to Foliar feed are 7-10Am and after 5 in the evening. This is because the stomata on the underside of the leaves are open then. Also, the best temperature is about 72 degrees, and over 80, they may not be open at all. So find the cooler part of the day if it's hot, and the warmer part of the day if it's cold out. You may need to spray at 2AM if that's the coolest time available. The sprayer used should atomize the solution to a very fine mist; find your best sprayer and use it for this. Make sure the PH is between 7 and 6.2. Use baking soda to make the solution higher PH, and vinegar to make the solution lower PH. It's better to spray more often and use less, than to drench the plants infrequently. Use a wetting agent to prevent the water from beading up, and thereby burning the leaves as they act as small prisms.Make sure you don't spray a hot bulb; better yet, spray only when the bulb has cooled.
Perhaps the best foliar feeding includes using seltzer water and plant food at the same time. This way, CO2 and nutrients are feed directly to the leaves in the same spray.
Foliar feeding is recognized in most of the literature as being a good way to get nutrients to the plant later when nutrient lockup problems could start to reduce intake from the roots.

I would only foliar feed epsom spray in cases of a mag defeciency to clear it up quickly,other than that I've never experienced the advantage.
