is GH flora series made for RO water or just tap water(should you add calmag+ to RO )

It's not meant for R/O water. You can call them yourself and ask as I just did. They specifically said that if you're using R/O water that a cal/mag suppliment is probably needed. The formula was put together years ago when R/O water wasn't as prevalent as it is now.

Give 'em a call and fact check me http://www.genhydro.com/genhydro_US/contact_us.html

I was intrigued by this statement so I took your advice and called them. I spoke to Nancy and she said that they weren't necessarily made for r/o water but that most of these nutrient companies do their testing and stuff with r/o or distilled water. She did say that you may need to add cal/mag depending on your strain, grow medium, etc.

yea MAY is the key word. I have used GH lucas w/ro for a long time and NEVER had to Mag sup . Lucas provides 107 ppm Ca and 60 PPM Mag which is more than even Botanicare Cal/Mag + GH has 5%Ca and 1.5% Mg. All nute tables PPM values are with RO water. You have to have a standard (reference), and RO is that standard

I didn't mean to say 'meant' as in 'specifically made for' I just used that word because I couldn't think of a better word to use.

When you look at the nutrient calculator page: http://www.genhydro.com/calculator/index.html the notes section states that the figures are based off using pure water, which probably lead me to use the word 'meant'. That and laziness.

Hey, how come the link I posted looks different then everybody else's?

Try Equilibrium instead of Cal-Mag with the R/O water. It has been great for me.

What is Equillibrium? Who makes it?
