Quick update
I did a water change on Thursday after work (pic from Saturday morning).
I had a lot of distractions when I was doing my last water change and I am almost certain that I didn't mix my
nutrients right last time. This plant is bouncing back way too fast for it to have had enough nutrients.
I don't have a TDS meter or any of that other fancy stuff. I just do water changes to keep my nutrients in check.
Anyway, this grow light works. It's the only
led light I've used so I don't know how it compares to others. I've been making a number of mistakes and my plant is still happy. I'm pretty new to Hydroponics and I have a lot to learn.
