No they really don't.
They love soil that is VERY SLIGHTLY acidic- pH 6.7- and remember that pH is a logarithmic scale and that means that for every pH point, you have a 10x multiplier for acidity. Acid loving plants include the azaleas, camellias, and rhododendrons, as well as orchids- They thrive at a pH about 10 TIMES more acidic than cannabis.
Never use Miracid, orchid food, or any 'acid loving plant' product on your cannabis plants.

You're going to have to re-pot, adding lime to bring the pH back to neutral. Peat moss is already acidic and it will be dropping off anyway, as soon as the lime is used up.
