The crayfish love to eat the plants and chop them up sometimes so I want to give the plants a fighting chance to live and produce.
funkman262, boredomb, 1077, Abstmind, and Byron, thank you for your input!
No one can tell you or I what nutrient's may be needed in what proportion (Plant's will).
Byron has eluded to the reason's (ie) fish waste,fish food's,plant mass,substrate composistion,CO2 or NON CO2,lighting,source water.
Flourish comprehensive work's for many,I have used it, but observed that the plant's were still stuggling in my tank.
Noted that the large jug of Flourish I bought said..."For macronurient's NPK, please see Seachem's Nitrogen,Phosphorous,Potassium."
I decided to add both the macronutrient's,along with Micro (Flourish) in small increment's until I achieved desired result's. Rather than trying to guess at what nutrient or nutrient's may be missing,I add a little bit of everything.
