PH is showing acidic today after replanting. What do I do?

So I tested my PH today after I replanted yesterday. I used a compost/manure mix. I posted yesterday after the replant that the PH was 6.6 but after checking again today it’s more like 5.6. What should I do? Baking soda in the water? If so how much and how often?

If you don’t have a growlog please answer these questions.
What strain are you growing? Is it Auto, Fem or Reg?
Are you growing Indoor or outdoor?
Are you using nutrients? Which ones? How much?

Peat moss? Maybe wait a couple of days and see if it fixes itself

I feel like soil meters really dont work

What is the best way to measure soil pH? I’m also having a lot of issues with acidic soil and doubting if the meter works…

A slurry test if you’re using a pH pen/meter for liquids.

Add distilled water at 2:1 to your soil sample and mix well. Wait 15-20 minutes and test pH of slurry
