what would happen if.....and foliar feeding

i know this will sound weird but what would happen even if just for a day u did the lights 2hrs on 2 off or 3-4hrs on or 3-4off or 2 to 1 ratio or any equation .what would happen inside the plant and how would it act and how much would it take of foliar feeding .i know its an odd question just curious if theres any light tricks at all other than getting one to flower
