Foxfarm Ocean Forest ph

[vtrob]

Hi All,
I am using Fox Farms Ocean Forest soil, in 10 gal pots. 2 girls just completing 3rd week of veg.
I used FFOF last time and had no issues at all.
A few nights ago I decided to ph check the water run off and was startled to see the ph was at 5 to 5.
I had been adjusting the water going in to 6.5. I then adjusted the water to flush them at almost 8. The run off is still measuring 5 to 5.5.
The girls look ok, but I am concerned.
Any yes I am a noobie, 2nd grow.
Any suggestions or comments would be welcome.
Thanks.

10gal pots??? Really??? A little over kill don't ya think??? I can picture you moving them around with a dolly :jointsmile:....

Likely salts have built up at the bottom of the massive pots you're using which has caused the pH drop in the runoff....

If they're looking good and keep growing good....then it shouldn't be much to worry about.... Just keep an eye on them....one thing is for sure....they have enough soil space....
