@jmystro so the water I’m using is filtered through an RO buddy and I add 2 to 3 ounces activated EM1 and some Mr fulvic. Ph 6-7. I’ve been using a fermented peach extract about once a week also. The smell only comes after it’s ran through my sprayer and I read it could be sulfur gas building up. First run using the sprayer. Only issue I’ve had is some curling on top leaves and slight yellowing almost looks like a iron deficiency, but also it’s the only plant that shot all the way to the lights so hope it’s just light stressing it. Sorry kinda got off track there but was just wanting to make sure that the egg smell from the sprayer wasn’t the problem or anything I was worried it was anaerobic bacteria, causing the smell.
