where to buy nutes online/pls help

Hello All. I am trying to find a quality place to buy nutes, like Ca. and Magnesium, online. As well as a pH tester for soil, not hydro. Any body have some good sites I can buy from? I have no stores in my area to buy nutes from. Please help.

i buy from growwurks.com. they are in cali.

ebay has some too

I checked Amazon, they seem to have a lot of stuff lol. I was surprised, because I don't really go to Ebay or Amazon, but seems they have lots of pot growing stuff lol. I have a few wks till I need the new nutes, so I am glad for you all's replies!

A simple google search would literally pull up hundreds of vendors. It's just a matter of finding the particular brand you want. Personally, I found the best deals on ebay.

htgsupply.com, theyve got good prices and theyre reliable.
