On the otherhand, there are certain plants that once introduced into a new tank tend to quickly melt due to transition to a new environment (ie. crypts) or are sensitive to certain chemicals or nutrient rich water (ie. too much excel for Vallisneria, or too much nutrients for fissidens), they may show deterioration even when parameters are optimal for the other plants in the tank.
Thats one of the reasons why people are puzzled why they see existing plant doing well while the other newly introduced plants are dying.
So while observation of the general growth of plants in a tank does help to gauge the suitability and stability of the tank conditions, you'll also have to take into account that there are differences in how individual plants react to specific parameters too.
