    Beware. I spritzed my plant with lights fairly close and it really fried a lot of leaves. The droplet magnifying effect.

    I never spray anything on my plants. I believe the possible negative effects outweigh any positive.

    The one exception was alternating between neem oil and baking soda to deal with a nasty fungus several years ago, likely septoria and probably partially caused by spraying stuff on the plants! (by the way the sprays did very little if anything to fight septoria, proper humidity/environment is the key to control .. and a sulfur burner):hump:

    .. if the canopy is not too thick (and if you're determined to spray) I would raise the lights, give spray 5-10 minutes to sit on the plant and then put a fan on it till it's dry
    -good luck!

    TBH I actually do that let it dry quickly as to not let it sit on the leaves

    I'll not spritz my plant's leaves again on any grow. I never used anything but water anyways. Too risky since I like to keep lights close. Question: Do CFL's also have the capability to cause the water droplet magnifying effect or is their light intensity not enough to do so?

    Spray just before lights out the plant will absorb the feed still.

    As long as the room temps aren't too low, otherwise, spritzing when the lights go out may cause mold/mildew growth in cooler environments.

    Spraying and letting them sit in the dark wet for hours is how I got brown leaf spot, aka septoria.

    .. there's so little benefit from foliar feeding or spraying anything on your plants for that matter, if they're healthy it's just bad practice in my opinion
    -good luck
