You are probably over feeding and cause a little nute burn. Try feeding with every other watering and at only 50% of the recommended dosing by the manufacturer. 6-7 pH is a pretty wide range. I take it you are using colored test strips that only give whole numbers? The ideal pH for soil is 6.5, 7 is too high. Either side of a correct pH range will cause something to lockout and build up in the soil. Check the chart.

The affected leaves will stay the same. You want to watch closely to make sure that it doesn't continue to spread more on the same leaves, or to other leaves. And give it a few days to make sure, it might continue a little more, even after you stop nutes.. But just be patient.
 
Luckily the brown spots stop spreading and just stayed at the tips of the leaves, so im guessing it was nute burn,
flushed with ph'd water and given no nutes since
