Soil ph

I just bought a ph tester pen and tested the runoff from my plants and the ph was at 4.8. What is the best way to get the soil ph back to normal.
Thanks for all the help.

What was the PH of the water before going through the soil? You can't just measure run off. You need to know the PH of water before and after to determine where the soil lies....

If the PH is truly that low, add some lime and water it in.

The ph of the water going in is at 7.0

hmm dam
uh u wanan get some ph adjuster
cause ur gonna need it since ur tap water isnt correct ph
man im glad my ph is awsome
i have a natural well since our house is old as dirt
so im getting all kinds of weird stuff but plants dont mind
i think it helps them

but in the end lime will do the trick just use carefully
