Yellow/white spots idk i need help

Okay so theres yellow/white lines and spots idk whatt this is but i think its when i sprayed with a sprayer on the top of the plants the t5 light burnt the tops of the leves? Any others think its something else? Besides that does it look healthy for 13 days old? (pics):

PS: No nuts just FFOF soil

hmm , how close were your lights above the plants when u sprayed? u really need to give your plants about 6 hours to dry up after spraying.i wouldnt worry about it just yet just see what happens.also your plants look decent for 2weeks
