You need to 'atomize' the spray, so use the finest nozzle you can to 'mist' the plants. Water has weight, so too much can cause plants to droop some, plus as stated above big drops can concentrate light on small spots causing light burn.

You can mist in the light, just do so early or late in the day while temps are low ('70s) and the stomata are open.

Lastly, if your plants are doing well as is, foliar feeding has a very limited impact but adds risk to the grow. I would reserve it for helping correct imbalances when they occur, or to help with drought.

RULE #1: Less is more.

Good luck.
