Hi,all -
I was wondering if any company designs their products for use with r.o.water - or do I need to add calcium + magnesium supplements?I'm using FloraNova grow w/superthrive for veg,and I have FloraNova bloom + Floralicious bloom additive.Do I need to add cal/mag or epsom salts?.

Yes there are companys with formulas for RO but not very many, as most is tap or hard water. Most likely you will need to add CAl-Mag, but check with the individual nutrient manufacturer.

MasterVaper... RO water is about 7.0 in ph and minimal ppm in total disolved solids. It's up to you to provide the rest. Your plants should tell you if you need to add magnesium... slight yellowing of leaves.

I use RO water with great success. My nutes are PBP, Liquid Karma, supplemented with a little Cal-Mag.

RO water should be just fine with any nutes out there.

I use Gh nutes with R.O. water. GH also makes a hardwater version that requies Cal-Mag. Good luck.

There are many nutrient brands that have a soft water formula ..i use ro and have had a few problems with trace mineral deficiency..but if you use a hydroponic nutrient with proper ratios of all macro secondary and trace minerals you should not have to add cal-mag to your solution...

take care

I've seen mention of RO water here a lot. Being a newbie I don't know what that stands for... Please elaborate. I'm sure I'll feel like a dumb ass one this is explained.

This is my RO unit... there are 6 filtration stages and it will put out 110 gallons per day.

My water was bad out of the tap... PH 7.5 and PPM about 600ish

With the RO unit... those numbers are PH 7.0 and PPM of 12

This unit was from ebay and under $150.00 delivered to my door.
