Ok, so 1 week into my grow with seedling finally planted into the clay pebbles and I find I’m having ph issues due to extreme hard water. I’m using the flora series and knowing we have hard water I purchased the hard water micro. Well. I purchased some ro water and re added nutes for this. Can I still use the hard water micro or use regular. What is missing or added that makes them different
Thanks

Sorry you didn’t get an answer. I may not be the one to answer your question but explain if you will hard water? High ppm’s high ph? And numbers that you’re reading.
I wonder if your up to other options as well.
We’ll get you some help.
I was able yo get a response from general hydroponics they said the gardwater micro and the regular micro are only different in that the hardwater has 2.5% calcium and the regular has 5% so i added cal mag and continue to use thehardwater formula. Plants are doing great. Thanks for the response

Good to hear you got it taken care of. 
I noticed you have HVAC experience. I can assure you you would be a big asset to the community. Folks are always asking AC questions.

One benefit about hard water is that you shouldn’t have major pH swings. The downside, getting the pH down to begin with. Glad its working out
