Who sells the pH perfect formulas? AN told me they are only sold in europe.
Who said that?
It's definitely not Europe only. They sell it in Canada too. Every state in the US gets to make up its own rules for product labeling so it's a nightmare of red tape to get anything new (as in not based on ancient fertilizer theory) allowed for sale in the States.
If you want to make a product based on plant science that was cutting edge when your grandpa was a young man, that's no problem. But if you want to build a formula around anything learned about plants in the last 40 years the state bureaucracy will fight you tooth and nail.
Depending on where you live you might be able to get it locally, I don't know. If not, you can buy it online. Get a good picture of the label on the bottle, the new formulas say "pH Perfect" right on the label, usually on a ribbon banner image. The new labels look different than the old ones. If you want to be extra careful, email the seller ahead of time to ask them which label they'll ship you.
