I have some soil soaking and will hopefully be getting the tank (around 200l) in 2 weeks. The tank will be low light max 1.75wpg and have pressurised co2. I'll be using mainly crypts as the plants.

Would it be worth adding some root tabs,- ADA multi bottom etc, at the base of each plant at the start just to kick start the plants or not?

I was thinking of weekly liquid ferts of traces and K. Does this sound ok? too much/little?

I don't think you need root tabs. They might supply more nutrients than your slow growth environment needs.

I wouldn't dose anything until there was a need. In most of my tanks I find that a little nitrate every now and then is enough, and my tanks have more light and faster growing plants than does yours.

You can do either, but it does not matter.
Nor is in more "convenient", you are already dosing ferts to the water column........what's one more item like KNO3 instead of K2SO4?
So all you might add is one more item(KH2PO4).

This is not a non CO2 tank though.
I'd do 2x a week though for the tank.
If you have a good fish load etc, you might be able to do pretty well with 1x a week.

Woops! I missed the fact that this was to be a CO2 tank.
