Utopia Haze Flowering need help Fast!

Hey guys im having a problem with my plant during its mid flowering stage I checked the guide to see if I had any nutrient deficiency and I got no help the strain im growing is called utopia haze. She was growing healthy up until 4-5 weeks into flowering some of the leaves are very rusty looking the tips looked burned I am almost certain that Im missing something in my mix? maybe you guys can help im growing in a 5gal smart pot with FFOF/Perlite/Lime, CFLs , Roots Organic Nutrients Buddah Grow, Buddah Bloom, and Trinity, also I add Bud Candy,Cal-mag, Big Bud...when I started seeing signs I flushed the plant thoroughly with tap water, let it sit for about a week then I fed her a teaspoon of bloom,trinity,bud candy,big bud,cal-mag, and 3 drops of superthrive to get her going. This was all mixed in a 1 gallon jug of RO water. I been feeding 1gal every 5 days using RO water/cal-mag every other watering. Maybe this is an NPK issue I dont know, as you can tell I am a noob and this is my frist grow. Please help I am about 1 month away from harvest and my plant looks good still but im concerned because leaves close to my buds are starting to rust HELP!

bumpppppppppppppppppp

anybody?!?!?

A bigger picture would help a lot, it kind of looks like nutrient burn but I can't tell whether it looks burnt or is bronzing. I would check your PH and get a better picture if possible and post both to here.

Edit: Also a picture of the whole plant would be awesome

certainly look's over watered! how close is your light?? way too hot on the nute's..what's your ppm??I'll bet you flush that plant check the run off and it's higher than what your adding....slow down and let it breeth i vege with cfl's these are three week old seedling's w/ no nutes yet..week four first feed 50% fox farm schedule...next feed 2nd week flower in soiless mix........

look guys I know its a pain in the ass to look at shitty quality pics but this is all I got at the moment as you can see some leave at the bottom are dying the tips look burned/rusty and im starting to see spots on the leaves growing with the colas any suggestions?

Sandiegojack2's got it all right there. Those look over watered and over nuted.

ha ok so ill just give them water for the next to feedings? should that help or should I flush when the soil dries up? I already flushed once I dont think another flush would be smart any input?
