I have two divided 10g tanks, and have always loved the natural plants over the plastic ones. The tank on the right was setup about 2-1/2 months or so ago. The one on the left is just about a month old. The top pic is what they looked like just a week ago - everything seemed to be thriving, green, and healthy. I did a scheduled 25% change on Wednesday. However, on Friday, the left tank plants leaves turned translucent, and I realized this was because of a nutrient deficiency. I added some plant food and liquid fert, and have the flora light on for 10-12 hours a day (normal routine). I've checked the levels and all are fine for now - except alk was a bit low, but that is all.
Should I toss and start over? I was wanting to try another substrate other than gravel, because I don't believe I have enough gravel and it doesn't do the plants any good. I've read up on the 'no rinse' substrate, and want to order some from Petco.
Also, for now, are the yellowing/translucent leaves bad for the tank/fish? Can they poison the water/fish? Can the plants recover from this?
Please don't criticize about plants. I love my tall swords because they keep the logs in place. I realize they will eventually outgrow the tank.
