hey rich, i just saw you want to know more about those plant hormones i told you about, the info is not super easy to find so i thought id share with you some info i found. https://manicbotanix.com/plant-hormones-phytohormones/
i took a screenshot of what i was talking about, they're called cytokinin and when they say tomatoes that apply to weed, most hydroponic foods are made for tomatoes. i know this may seem like little evidence but I've seen serious breeders talk about this, guys that been growing for +15 years and over 10 in commercial operations so this is used in many food industries, all this compounds are natural and "organic"
