Ph problem?

[NoobgrowerS]

Hi.
I recently begun to have this ph problem and i don't know what causing it.

I transplanted my grow from 10l plastic pots to 22l smart pots.
Adding some soil in the bottom and space around, same soil.
Ph up to 6,5-6,7, all fine but,,,, runoff is 5,9-6,0.
Before transplant i watered with ph 6,3-ish and runoff was 6,5-6,6.

Why is runoff so more acidic now? Any ideas?

Has been like this 3 times watering now. Can't see any problem on the grow.

No big changes then before transplant confuses me.

Fresh soil in transplant means fresh nutes and soil

Bet the girls are snuggling up to the nutes and drinking em up.
My runnoff was always less pH than I watered with, so sounds like all is good
I wouldn't worry a bunch about small runoff changes

I've noticed speed of water pour effects my runoff pH, so stopped checking it as much

Yeah. They looks fine to me so not really worried. Just confused why the ph dropped. Didn't have that ph when i read runoff in the beginning with all new soil. No big deal,,, they seem happy

Get some garden lime top dressed to where your runoff is 6.5 -7.0 Nitro, Phos, Calcium, magnesium, potassium, all locked out under 6. No problems now could just mean there is still plenty of the goods in the plant tissues but when it tries to keep growing you could get massive symptoms.
