You will want to modify this and add some KH2PO4.
Perhaps GH booster as well after water changes.

Note, you should not mix PO4 and Fe/traces together in solution.
So you need two solutions to dose from into your tank.

Realized too late that those fertilizers should be seperated.My GH is extremely low so your right that it should be supplemented. After replacing a broken light fixture with a better lighting system my tank has been out of balance. There is a huge increase in pearling but certain plants such as a water lily that is losing leaves rapidily.Also a few other plants seem to be growing vertical as opposed to horizontal. Thanks for the feedback.
