Is that 8 or 9 weeks of 12/12…?
Some strains take up to 12 to 16 weeks of 12/12 lighting schedule before they finish…
Usually the sativa dominat strains…
The indica dominant strains usually 8 to 10 weeks…
Hybrid strains usually 9 to 11 weeks…

Im not sure if rock wool makes it different but 5.7 is kinda low for soil and can cause lockout and slowed bud growth and and depending on your other environmental factors a fluctuation of 20 to 50% is a big swing in my personal opinion. Possible environmental stress. I dealt with environmental issues a few times cause of texas heat. And lastly, it looks you still have a ways to go flowering her out

Peach covered most of it.
Typically rock wool isn’t mixed with soil, but looks like it’s not causing any issues.
Some strains take longer than others as peach fuzz mentioned.
