Hi there.
Yes a company in Holland called Ferro
This guys make excellent nutriants and they are area specific. They look at your local water table and make custum nutrients for your area.
I am using there Growth A and B part nutrient and its doing wonders.
I dont have to realy adjust the PH because they have take that into account from your local tap water also if you have hard or soft water in your area.
I may have to put a couple of drops of ph down after a few days but thats it.
Heres there website. I buy from the UK but they are based in holland so you must be able to get it somewhere.
