Question Melting R. rotundifolia and S. subulata

Greetings all.

It's been 7 days since the plants have been in the setup and I've noticed quite a bit of melt going on. Subtstrate is Eco-Complete with Osmocote Plus added and I dose 2mL of ThriveC twice a week. Photoperiod is 6 hours and light intensity has just been increased to 50% power. My build info is here:

Water parameters:

pH = 6.7
Ammonia = 0.3 ppm
Nirite = 0.5 ppm
Nitrate = 20 ppm
GH = 3
dKH = 10
TDS = 434

The Rotala has new growth on top, but the old growth is looking pretty poor and seems to have lost a lot of it's pinkish color. Some stems have melted completely.

The Sagittaria has melt as well and the leaves that are still green look in rough shape.

I know it has only been 7 days since planting, but I'm curious if the plants will bounce back given time or could they be showing signs of deficiency?

I appreciate any insight and advice on this.

Normal: most plants purchased on-line are grown emersed and will die back when newly planted, as well as plants moved from a tank with radically different parameters. They will come back as long as they aren't being poisoned and i don't see evidence of that.

Yah, just give it time. If you see new growth, it's heading in the right direction.

Thank you Deanna and MissCris. I'll give them time to acclimate and keep my eyes open for changes.

Your tank is still cycling, melting is very common in new tanks, as long as the stem or rhizome is healthy it should bounce back. I would do at least 2 50% water changes per week until you no longer see any ammonia or nitrite. It also helps to cut back melted leaves so that the plant will focus on the newer healthy ones.
