Yea i do it myself when seedling with low light intensity maybe try to get a finer mist on them if possible but i know when i switch to my 1200 watt leds im more careful about spraying if i do a foiler feed i try to do it within 10 minutes of lights being off so your plant can still uptake the nutrients at that time if u wait more than that while lights are off the leaves wont absorb it
