Stop doing that. Fish emulsion is one of the best plant foods you can give your girls in veg, but it needs to be given to them through the roots.
Foliar feeding, what your doing by spraying the leaves with a food solution, is not necessary unless you know exactly what you are doing. If you don't, you run the risk of contaminating the leaf surface and interfering with photosynthesis at best and double dosing the plats with food at worst. Feed them what is recommended on the bottle through the roots and you wont go wrong.
Good luck.
