I don't think it was really you. I'll add some medicated feedback after having just scrolled back through...and I assume your water PH was good going in at ~mid 6s throughout
Your plants looked like they wanted to be monsters, and were pretty healthy...I don't think they got enough to drink, because plants like that can drink way more in soil than I could ever effectively hand-water them in a cloth bag. I've only ever grown autos that are water-only in organic soil, and once I went to aerated SIPs, the water consumption, health, and growth of plants has been dramatically different, fwiw.
