What should I PH my water at in canna terra professional soil?

Hi just a quick question as I’ve seen elsewhere that I should be watering at 5.6 - 6.3 in canna terra professional soil, I’ve only just read this (onto day 15 of veg only watered around 3 times). What’s the best ph range I should be aiming for? Thanks

If it's pH buffered you don't need to pH your water/nutes

I use Promix HP which is pH at 6.5 I believe

My water/nutes is 5.8-6.5 depends on RO or tap water

Never an issue

My tap water ph is quite high it’s usually around 7.5, after mixing nutes I’m left with the water at 6.7 - 6.8, should I lower that a tad or just feed it in?

If it's buffered at 6.5, should be fine

Maybe find what the buffer pH is, make sure it's not at 5.8 or something goofy

I checked the run off on one of my back pots and it was at 5.7, my other 2 were at 6.3

Run off means nothing, don't test it

What does the MANUFACTURER say it's buffered at, probably on the bag
