First off how do the plants look?
They are looking good
But still long way to go so I wanted to be sure everything goes according to plan....but low soil ph is not good....I'm currently on Advanced Nutrients

excess P and K can acidify the soil. I take it it’s peat based soil?
lay off the nutes a bit unless you are 100% sure it’s the right amount for their age.
Most seem to pH at 6.5
But you can feed higher pH to offset a low pH (within reason)

I wouldn't make any sort of decisions based on runoff pH, myself. Get some distilled water and measure the soil pH directly by taking a sample and letting it settle if you must know soil pH but unless you're having nutrient uptake issues I wouldn't bother.
Are you pH'ing the water you're giving your plants? That's what I'd do to start. Get that in the 6.0-6.5 range, maybe start at the higher end of that range initially to get your soil back in range more quickly.

I'm buying Canna Organic soil....using perlite as well....I'll try to lay off the nutes for sure maybe it will help....thanks

If he’s in peat you get issues under 5.0 in my experience. Especially during flowering when salts build up in the media.
I measured the soil and it was 5.3 no probs. 4.8 mag def and trace elements.
I’ve read recently that plants excrete acids or alkaline substance around their roots.
I think this may apply to MJ too. Obviously if the pH is too far out of the range then issue will occur.
also each strain can handle different pHs..
