Sounds like ProMixBX...
I personally can't STAND peat soils. Even if they are properly pH stabilized (good luck, eh!), the water retention qualities aren't ideal. I'd add a bit more perlite to the mix if you want to use that one.
I have said this a hundred times and I will probably say it a hundred times more, go to Agway, get a sack of manure with humus, add ~40% perlite, watch your plants grow happily.
