Brown/purple tips on top buds

Week 7 of growing gorilla cookies auto from fastbuds, the buds have developed these brown tips, is this normal? Lower buds look better.

I've had what i think is a nutrient burn issue on this plant since the begining, even after flushing multiple times it doesn't seem to go away, attribute it to the potting mix i used, weirdly the runoff always has a ph of around 7 even though i've been phing the feed down to <5.5 since a month.
