Yellow marks

I have noticed these marks ob my plants from the day when i sprayed them with lemon juice mixed with water for spider mite prevention....Can anyone tell me

Also i have my Cfl 23W around 10cm away of my plant...is that too close and maybe caused light burns?

Why the hell are you spraying lemon juice on a damn seedling? Leave that seedling alone and let it grow. You're going to love it to death. Put the lemon juice down, walk away from the plant, take a deep breath, go eight hours without looking at it, smoke a bowl.

Good luck.

It was because i spotted 2 spider mites on my plant and didnt want them to spread so i increased the humidity for one night and sprayed them and it worked so dont say its a stupid solution cuz it worked and its organic

Like I said. Good luck.
