I bought some Brazilian Micro Swords (Lilaeopsis Brasiliensis) online and they ended up spending 7 days in transit. This didn't seem to affect the plants too much, but I live in Phoenix, AZ so that heat doesn't help. I planted root tabs under them before planting the swords and made sure they got plenty of light, but the plants are dying anyways. However. there is a small amount of new growth and am hoping it continues. I am wondering if I should just wait for the rest of the old leaves to die off and focus on the new growth or if there is a way to bring the old leaves back to life. (I included pictures of its progression)
