I got some pictures of some of the plants with the problems. Click on the thumbnails to enlarge.
My test kit shows 20ppm of nitrate. I would assume phosphate is low, because I feed very little. There are only 6 oto cats in the tank so I let them eat naturally for the most part. I am not sure how I would have any potassium, so I am assuming that is the biggest deficiency. What should I look for the find the city water parameters? Is it worth buying a phosphate test kit?
