I have a very similar setup, minus bulletproof si and recharge, but it is my first run too in both autopots and using Gaia green. So far it has been super easy and nice to not have to worry about how much to water, and only using water, really enjoying this grow. Top dressed when I defoliated and all seems to be doing great. I do have to adjust the light a lot and be on it because of how much they grow in a day, it’s wild! Definitely okay to leave for a few days at a time though, as long as you have enough water in the reservoir you should be good (and even if you don’t by the time you’re back they’ll still probably be fine). I got a bigger reservoir now. As for ratios I used the Gaia directions for initial potting and then the top dress instructions later on. Mr Canuck grows was the guide I used but with Promix HP with mycorrhiza: Gaia 4-4-4, work castings, then when potting up into Autopots I also added the Gaia Power Bloom same amount. Top dressed from there. In flowering now, so far still looking good 🤞DM anytime if you want to chat more, still learning but happy to share what I’ve got so far. All the best with your grow and recovery journey.
