I’m running a 2 site rdwc with ionic nutrients and hydroguard, I keep reading about humic/fulvic acid being good for soil and hydro plants but I don’t know if it will be ok to do with hydroguard thanks for any help
It will do fine, but will stain your roots brown.
Thank you very much, do you think its worth it to use
I only used it in soil. If you feel it’s beneficial then sure. It’s a secondary nutrient. I’m sure it helps, but if you don’t get the proper NPK ratio then it won’t matter.
