I have nothing to sell you, nor would I set you on the wrong path...and thusly have nothing to gain in offering you misinformation. Are you sure they are recommending 6.0 ph for cannabis in a peat-based soil? If so...they're wrong, and should be soundly thrashed. (and set-straight) :thumbsup:

Takes a couple of months for the lime in the potting soil to degrade, depending on how much buffering it's being forced to do. (the lower the ph, the harder it has to work to buffer the ph...so it's depleted quicker)

Keep in mind that the nutes are (in my experience) acidic, and will lower your ph even further. (a couple of points, minimum for full nutrient compliment)

Organics degrade slower than chemical ferts, (which are broken-down already, and are ready for plant uptake) so careful with the organics. They can and will build-up if not careful.

Ever have a burn or rash on your feet? That's about what the plants feel like while you are burning their feet with acidic conditions. (irritable, tender and stressed) I'd do a mini-flush (equal to the volume of the pot) with water at 6.8 or so. I'd do this before adjusting the nutrients.

Usually it's best to solve problems, and watch for results. Would suck to jump the gun and screw them up even worse. Patience. :jointsmile:
I couldn't have said this any better! :thumbsup:
