the plants are probably just getting used to the new conditions and shedding the old foliage to adjust to the conditions, I have had melts moving a plant from one tank to another with the only difference being the substrate so I think it will turn out fine

Thanks for replays, but i dont think its it. It dosent look like deficiency they turning brown and die. Becoming mushy. Even java fern turned almost black in 2 days
