pls help newer leaves brown and yellow

4 weeks into flowering 12/12 light using 6x 85 watt 3000k cfls, miracle grow moisture control potting soil
This plant I believe was over fertilized along with another sister I flushed both but this lady continues to get worse and i dont know what to do please help its mainly on the newer upper leaves throughout the leaves and in some lower fan leaves just around the edges , dunno if its related but i have seen a knat flying around very rarely






2nd plant

leaves curling up this looks like what i first noticed and thought was nutrient burn flushed this plant as well but doesnt really get better and i just see more and more leaves affected

Bump for you dude! I hope you get an answer.

not sure myself, but it's not nute burn
lights too close?
soil too wet, possibly
pH
could be Fe or Mg
sorry man, i don't know, but somebody does
