I purchased some new plants from petsmart that looked fairly healthy, however since planting them in the tank many leaves have started dropping off. I am concerned I may lose the plants, so I was curious what I can do to help get it happier.
Unfortunately I have promptly forgot the exact name of what I bought, however please find pics attached that should help identify then.
2 x 17w full spectrum bulbs
Ammonia, Nitrate, Nitrite all 0.
Substrate is black diamond, and I have put root tabs down by the plants.
Hope I am wrong but that looks like hedge plant to me. Alternanthera ficoidea var. 'green' is not a plant that can grow underwater for long.
Looks like ludwigia repens to me (just has been nutrient deprived and in lower light). Losing leaves on ludwigia is very common when its adapting. Give it a few weeks and it should perk up. Make sure to cut off the new tops and replant them in th substrate (you can remove the old ones if they don't bounce back). It should start turning red if you have high iron and adequate light but can be grown green and still be "healthy".
Also look at the tips of the plant after the lights go out at night. If you see the uppermost leaves begin to curl upwards, its probably okay! They should flatten out in the daylight.

Reason: Added additional info
Zero nitrates is something you should probably avoid. Like almost everything else, they'll feed from both roots and leaves. Try a small bottle of Seachem Flourish, dose as recommended, and wait a few weeks.
But they'll take a couple weeks to adjust to your tank in any case. Patience.
