So is it necessary to flush? Was told other day it wasn’t needed.

Chelation is a type of bonding of ions and molecules to metal ions. It involves the formation or presence of two or more separate coordinate bonds between a polydentate (multiple bonded) ligand and a single central atom.[1][2] These ligands are called chelants, chelators, chelating agents, or sequestering agents. They are usually organic compounds, but this is not a necessity, as in the case of zinc and its use as a maintenance therapy to prevent the absorption of copper in people with Wilson's disease.[3]

Chelation is useful in applications such as providing nutritional supplements, in chelation therapy to remove toxic metals from the body, as contrast agents in MRI scanning, in manufacturing using homogeneous catalysts, in chemical water treatment to assist in the removal of metals, and in fertilizers.

I totally hear ya man. Citric acid works like that to help remove some Ca from soil. Breaks some chemical bond and allows it to get flushed out of the soil easier.

I'm doing organics so no flushing debate for me. I'd be curious what @Renfro 's thought is on flushing in hydro though.

That is what I use. It's what many professional flushing agents contain. Some contain ascorbic acid too. I use citric acid for the main pH down too. Works good for me using Promix HP.

Definitely. Feed according to the plants requirements. In early flower the need for feed goes up. During ripening the need goes down but it still exists. A feed that is properly balanced for the life cycle will always provide better results than one that is not. Too much nitrogen in later flower for example is bad but that doesn't mean we should deny the plant access to potassium.
