Thanks for the suggestion Dominic.. I think this may be a more viable
solution to solving the problem. Are these amounts from calculations or
just pure observation of what worked for you ?

This is from Tom's Estimative Index. I do not have a link to that
article. Search this group or fins.actwin.com/aquatic-plants for more
information on that.
Also my water parameters are almost similar to yours.
