PH Imbalance Confirmation

Background: White Widow in soil 76 days old, 16 days flowering. Fertilised at day 65 with a weak solution of Miracle Grow (15:13:12). By weak I mean half what packet directed.

Day 70 plant looked fine, but 6 days on all the leaves are turning brown - especially at the tips. I looked up all the faqs I could and it seems to be Ph Imbalance. I measured and its a tad over 6.5 which I'm pretty sure is in an OK range. My other plants which are now massive were treated the same but aren't showing the same effects (although their Ph is closer to 7).

Compared to my other strains it seems the buds are more wispy , there is less of them, and it seems to not be growing as much.

So question is: Is it Ph imbalance, or something else? And will it bounce back if I correct the problem?
