Wats Wrong Here?? +Rep

I cant work out wat is wrong with this??
The strain is Super Silver Haze.
My PH sits around 6.5, but drops to 5.8 sometimes..
There was only a handful on the plant, and the affected leaves r not the closest to my HPS (those ones r fine), n the temp is about 80degrees F.
One is burnt from the edge in, and the other is not burnt.. but is an odd color from the inside out.

It is about 4 weeks in2 flower and my food has not been too strong, and i flush regularly.. any ideas guys?? +Rep will b given.. Thanks

lacks nutes

I doubt that it lacks nutes.. Looks like excessive Potassium. It locks out other nutes and affects the uptake of magnesium, manganese, zinc and iron and calcium.
Here is a plant with excess potassium:

well

how do you fix it

flush it and give it straight water for a week or two then once recovered give it 1/2 strength nutes every 14 days

Flush Like a Mofo! Let it all get right outta ur soil before adding more nutrients.
Monitor PH closely during this time also as it will be important that u can uptake ur Cal + Mag. (6.5 - 7.0 in soil).
