This week the new growth of the plants transitioned from looking relatively healthy to droopy and yellowed. I wasn't sure what the issue was at first and thought it might be light stress. After more research, I determined that I had what looked very much like a zinc deficiency, which is almost always a symptom of over-watering, which is the most common mistake for new growers, i.e. "Me". I had assumed that adding a good amount of perlite to my soil and using smart pots would prevent me from running in to any drainage issues but I guess not. I was up to 1.5 liters per plant when I realized that it was too much.
I also realized I was misreading my syringe which I use to mix nutrients, and that i had been giving only 1/10 of the liquid nutrients that I thought. I'm super embarrassed about the mistake but I'm going for full transparency here, so there it is. Course correction takes places after day 31.
