Been there done that lol. The leaves will most likely get crispy and die. If you are in veg I suggest, remove the damaged leaves and let the plant focus on growing new leaves rather than being in repair mode. Spider mites are my worst fear now. I ended up ordering new seeds and culling my perpetual grow. I used a water/bleach solution and went to town on everything! Walls, lights, carbon filter etc. remove any dead leaves and give them nothing to feed on if you go down this path!!
I learnt real quick to keep my grow rooms as sterile as possible and don’t let pets into your grow room!
Good luck, hope all goes well man!
