DIY Macro Root Tabs

Hi all,

It's fairly difficult to find good macro tabs in Australia, most release Ammonia which of course isn't great for fish.

I use Seachem Root Tabs for my Amazon Sword and Banana Plant, replaced each month. However, they are pretty much micro nutrients with little NPK.

I have KNO3+K2SO4, KH2PO4 and K2SO powders for dosing. Could I freeze a small amount of power in an ice cube and use that as a root tab?

Low tech plant, no CO2. Have a Fluval Fresh and Planted 2.0, but it's dimmed down to about 50% or just under (at a guess). Standard 3ft tank with Nitrates always 10-40ppm with weekly 50% water changes or 2x 30% water changes per week. Maybe CO2 in the future, but a canister filter is the next purchase to replace the two cheap HOBs I have running.

Can you get Osmocote+ in Australia? This is what a lot of people use for DIY root tabs.

This is the closest we have, although @Seattle_Aquarist mentioned it has a high % of ammonia, so not very good with fish

Although with macro water column dosing, the Seachem Flourish root tabs for the swords might be enough.
Haven't started the macro dosing yet, but would only need miniscule amounts given it's low tech.
New leaves on the sword have a netted effect which is Mn deficiency. Our drinking water used to have very high levels of Manganese, but they built a water treatment plant to get rid of it. Not sure what to dose to help with Mn apart from Flourish. I only dose flourish once a week at the recommended dose (5mL per 200L), so should probably increase
