It would be interesting to know how many different formulas of MSU type fertilizers are being sold and used. There are many people selling it under their own labels and I wonder if they are all actually from the same bulk supplier.
Everyone please post where you buy your MSU fertilizer from and what formula you use. Post a link to the suppliers webpage if possible. This is not meant to endorse suppliers or brands but rather to learn what is available and from where.

I buy mine from First Rays. The formula is 13-3-15-8Ca-2Mg
 
I get mine right from Blackmore. I think it is the same breakdown as yours (I don't have a label anywhere handy). I certainly didn't customize it in any way. RO Special and Well water special are the only two I've ever bought.
 
Ditto to Lance. And that reminds me I need to place my order this weekend as I'm starting to get low.
 
I think I got mine at First Rays... I do not use it all of the time. I still use dyna-grow 795/Ca-Mg fert mixture as much as I use MSU. And use RO water.

If you have not read the 5 part article written by Bill Argo, Phd. (2003 IPA journal) it provides a comprehensive overview of water, fert, substrate, ph etc. Don't laugh I review it weekly and recently started to do pour through tests. Still learning and tweaking.
 
Got mine from orchidmix.com. The pure water formula is 12-6-13, the tap water formula is 17-9-18, the former with 7% Ca and the latter with 4%, and the tap water formula has no magnesium for some reason. I actually don't like how coarse this fertilizer is (takes longer to dissolve), so I'll probably get it from a different vendor next time.

I get mine from Fred Clarke at Sunset Valley Orchids. He uses a version the folks at MSU help design for water on the west coast.

I also use orchidmix pure water from Robert's flower supply. The pure water formula dissolves well for me, especially when I add superthrive to it.
 
Fred worked with MSU to develop their fertilizer for the west coast region. I don't know the details, but Fred said the water on the west coast differs from the east coast (i don't know if it's PH related or something else). I do know the fertilizer works well from personal usage and it mixes well with my RO water.

I call Fred to place orders. You can email him and ask detailed info.

I sent Fred an email and gave him a link to this thread.
 
I bought mine from First Ray's awhile back. I figured if I'm paying to ship a heavy box of clay rocks, they can ship an extra 5 pounds of fertilizer too.
