Hi

Have you guys bumped up the K concentration in Flourish K again? Just recieved a bottle at 5% K/5.8% K20. I'll check when I get back, but has it gone from 4 to 4.7 to 5%?

Thanks,
Nick

Flourish Potassium has been a 5% K solution for a little more than a year now. It's original formulation of 4% K has to be expressed in terms of K2O (4.7%) due to some state regulations. So it only went through one reformulation from it's original 4% K (4.7% K2O) to it's current 5% K (5.8% K2O).
