Oh yeah that's clearly... just by looking at the pics sprayed with something on the leaves. I did it one my very first grow attempt (which failed by week 2..but learned from it quite a lot)
The white spots may be from the lighting burning whatever is sprayed on the leaves... I can tell more from the white lines that sort of look like a stain on a carpet.
Once they sprouted(the seedling) then you no longer need to use a spray can.. just water...
