Left for vacation for the week, had my 13 yr old sister take care of my new tank. She did a great job but something is wrong with a couple of them. I have just been giving them Flourish and Flourish Excel. Some crypts were rotted (planted them wrong) and a couple of the plants have markings on them. Here's the pics.
The first one has greyish markings on some of the bottom leaves. The second stem plants has dark markings on it's middle leaves. The last plant just has one area of brownish markings (Algae?). I use a 5600k spectrum light, they get about 12-14 hours of light each day. While I was away some days they got 24+ hours of light. I use Excel almost everyday and regular Flourish once every 3 or 4. The substrate is good - made for plants - that kind of stuff. Can you help me figure out what is wrong and how to fix it? Thank you.
