Hello, ideally you should perform an EC or TDS and pH analysis on this water since being carbonated it should be mineral type. At least in my country, there are many brands sold as purified with high EC levels and a pH that leaves much to be desired. Now, if I made some changes, if that mineral in the water contains something that the plants are lacking, it could be an issue. But if you’re using complete lines of base nutrients and additives, this shouldn’t be the case. I hope I helped you, cheers!
