Hey gum
Hope you don't mind my 2 cents on lime.
It's used to raise ph levels and it's also calcium so it can be used as a plant food supplement.
I'd only pre treat soil if it had a very low original ph reading. It's possible that the addition of lime has raised your soil ph above neutral which could cause some nute lockouts.
Certainly calcium is required by the plant but it should really be in balance with all the other nutes and definitely at lower mean levels than the NPK of the medium or it could cause a toxicity.
Personally I tend to add a pinch of lime and 2 pinches of epsom salts to 1 litre of warm water and use it as a feed if a plant looks like it has a deficiency. The heavy feeders seem to need it more.
It might be worth just checking your soil ph to see where you are at, that would tell you what ph water would be most effective for flushing if it's needed. They do really cheap soil test kits at any garden centre.
