I just started a 20 gal. tank a week ago with Amazon sword, dwarf hairgrass, and s.repens. I started adding apI co2 booster half way through the first week. After the first day I seen plant growth on the Amazon sword new leafs were popping up by the third day the new leafs were melting. What could it be?

Swords are heavy root feeders so they would benefit from root tabs.

I put root tabs in the first day directly in front of them

I only have 15w t8 floral max light could that be the problem.

What kind of lighting do you have?

Edit: Just read your last post. Is this a 20 tall? Might not be strong enough but I'm not sure.

I'd give it some time honestly. It's not uncommon to have some melt as plants get adjusted to your tank.

Some swords will melt until the establish their root system in your tank. Once established it grows new leaves pretty quick. I have a sword. Leaves were about 8 to 10 inches tall. Started to see some melt. Then my two year old took it upon herself to try and replant my whole tank. Snapped and bent most of the leaves. I waited to see how many leaves were doomed. Snipped off all but two. Now I have four new leaves coming up the center only 7 days later. By the way she is grounded til she's 30!

Ok I'm pretty sure the tank hasn't even cycled through yet

Cycling shouldn't affect them.

Yes, cut off the dying parts so nutrients aren't wasted going to those leaves.

And if the light isn't getting down far enough do you think it would be a good idea to rotate the light around the tank so it is like right in front of the plants that are struggling

Do you know the par of that light for your tank size? I'm not sure if rotating the light would help.

PAR value of the light. I'm not able to link you to a good article since I'm on my phone but will try when I get home.

That's good if the leaves are improving.

I'm going to try and pick up another light today. I don't think the light is strong enough for them.
