PH of run off water 5.5

[Wookie0586]

Greetings fellow humans,
I'm doing my first grow in 20+ years.
I'm using fox farms happy frog soil.
Seedlings popped through the ground about a month ago. For the first watering's I ph'd the water to 6.5.
As soon as I was watering enough to get run off (I up potted to soon as I have learned from reading on this sight) run-off was 5.5. I've been ph'ing the water to 6.9 since then but the run off has stayed at 5.5.
The girls are looking great, growing maybe a little slower than I had anticipated / seen in some other grow journals here.
Is there anything else I can do or should I even be worried about this?
Should I be lowering the ph of my water?
Thanks!

I'm not sure why so many people care about the runoff in soil. I personally don't. There's so many amendments / microbes / buffers etc in decent soil (such as happy frog), that your runoff will almost always have a whack number. Trying to adjust that can be harmful. Only worry about the PH going in, 6.5.
