Day 20:
The plant didn't look super healthy and showed signs of nitrogen toxicity. I wasn't using a whole lot of fertilizer back then so I had no idea as to what was going on. Turns out my tap water is basically poison for young plants. It contains too much nitrate which explains the leaves clawing. I didn't care enough about this plant to flush out the excess nitrate that added up over time so I just switched to distilled and later on ro water with synthetic nutrients. Took me a while to figure that one out. My tap water's calmag ratio was perfect and I had no issues with chlorine either.
