Last weekend I cleaned the algae off the top of my pods, but then I noticed that my Pak Choi was starting to look sad. A few days later, I then noticed that there was a tiny transparent worm in the soil. I immediately took the worm out and treated the pod with diluted hydrogen peroxide, rinsed it with water and squeezed all of the water out good. I also made sure to clean the u-shaped lid and the cup that the pod rests in. The Pak Choi started to look like its normal self again. It’s now 4 days later and I realized that there’s some yellowing in the leaves. The water tank is about half full and the soil isn’t too moist. I’m not too sure if the plant is diseased or it’s not getting enough nutrients or if I should get rid of it and start all over. I took two pictures and hoping that someone can help me lol. I tried to do some research on my own but that didn’t work out too well. There currently aren’t any bugs or worms in site. Thanks in advance!
