How different is rice husk from coco peat, given that coco peat absorbs Ca and Mg, so Ca and Mg need to be supplemented the first year in coco peat, is it same for rice husk. How is the water retention in rice husk?

No, rice husk doesnt have this issue... but it decomposes relatively quickly... nonetheless it is nice medium for soil-less growing

So I will just need 20-20-20 and rice husk to start?

I would suggest to soak rice husk overnight in water to completely absorb water... use Mono Ammonium Phosphate 1 gm in 2 liter twice weekly for one month... this will boost the root growth and after one month you can start 20:20:20...
