Does anyone have experience at making CO2 in a 2 l...

Whoa, hold up there! A PPFD of 2210 is extremely high honestly, it's way past the saturation point for cannabis unless you are running a professional, sealed room with massive amounts of supplemental CO2. Even then, that number is pushing it. The yeast and sugar method in a 2-liter bottle is a classic DIY trick, but it won't produce anywhere near the levels of CO2 needed to help a plant process that much light. It's like trying to put out a forest fire with a water pistol. Your plant looks stressed and is likely light-bleaching or suffering from major transpiration issues at that intensity. You should definitely raise your lights significantly or dim them down to a more manageable range, like 800-1000 PPFD, before you fry her completely. Dialing back the light will do way more for her health than a DIY yeast bottle ever could. Happy Growing Growmie🌱
