Pant problem help please

my biggest plant has about 4 leaves with this problem on them other then that it looks fine i would like to know if some1 could tell me whats going on and how to correct it before anymore leaves get ruined im in the 3rd week of flowering

ok next........... i doubt it will be going downhill from there the rest are in perfect condition but thanks for trying to ruin my hope or whatever your lame ass was striving for

can you put some more clear pics? it's too unclear , try to adjust the exposure of your camera. From what I can see (but it's unclear) looks like a burn (either nutrient or light) Give some more details about your plant. What are you using? soil or hydro? what type of lights and what distance from the affected leaves?how much are you feeding her and what?

Dude, turn off the HPS and take some pics. And as perkele said more info.
