I did a water change on 06/14 and I saw it has some algae in there and I cleaned it up with citric acid, mixed 5 teaspoons of veg+bloom and brought the ph down to about 6 by eyeballing it since I’ve done this many times at this point.
But today 06/27 I want to top it off and check on it first cause I knew I had algae, and I see this. I don’t think I’ve experienced this much debris before? I don’t know what it is. I knew my plants were yellowing and today I got the chance to take the time to go through the roots and water. The roots seem fine, I just don’t know what to do for the water.

I cleaned the tank again, put 4 teaspoons of the food and got the ph to 6 with the ph meter.

Any suggestions or advice?

I have a Gardyn hydroponic system and this is my first time using my own spinach seeds I got online, and they won’t germinate!! I put 6 seeds in the pod and nothing happened after almost 3 weeks, I started a new one and used warm water in it cause I thought maybe having a heat source could give it a boost since the seeds are so big… and still nothing after 2 weeks. I thought of buying new seeds from another website but wanted to see if there was something I am doing wrong.
I also struggled with the cilantro seeds and when I used warm water, it germinated the second time.
