Help with planted aquarium

[C.w.deegan]

I recently decided to get rid of the artificial stuff in my tank and I purchased a bundle of 18 plants online. The plants arrived and all looked healthy I planted them in my 38 gallon tank and put seachem flourish tabs in the gravle and the flourish liquid in the water all the plants were supposed to be easy care hardy plants its been about a week and a few of them dropped all their leaves and died and a couple other ones look like they are turning brown im not sure if I'm doing something wrong this is the first time I tried a planted aquarium any info or advice would be great.
The tank is a 38 gallon bowfront with a tetra hob filter its a live bearer community tank with Cory's plattys mollies and sword tails
Ammonia is 0.25ppm Nitrate is 20ppm nitrite is 0.5ppm ph is 7.5 and water is hard local water supply is really hard water

Plant melt is normal when introducing new plants to an aquarium.

Commercially sold plants are cultuvated immersed rather than submerged in water. This way they have ready access to CO2 from the atmosphere and will grow much quicker and be more commercially viable. The downside is that the plant then has to adapt to new conditions when put in an aquarium, leafs that have had ready access to CO2 will struggle without it and may die off. Its possible to lose all your original growth, but new growth should be tolerant to being submerged. A week isnt really long enough to judge new plants.

Remove any dead or dying leafs so the plant can concentrate its efforts on new growth.

Are you seeing any new growth yet?

A couple of them have grown a little bit but most of them just shed the leaves and I haven't seem any new growth since then in the ones that shed

Its only been a week. Those plants dont look in too bad a shape for being introduced a week.
