Here is the weight chart for the russian tortoise that I hatched last year. I hope the chart stays lined up.

Now there is some variety among Med. torts. I doubt a marginated tort would grow at the same rate as a russian or a hermann's, and it seems some varieties of greeks are larger than others.
And as you see above, my tort didn't grow at a steady rate at all times. Could be I overfed him, too. But at 15 months he is 224 grams and 4"/101.6mm.
I fed him clover, dandelions, henbit, hibiscus, other weeds, grocery greens, mazuri/timothy hay mix. Calcium/d3 and sometimes repcal multi-vitamin. Starting in April this year he moved to an outdoor pen. When outdoors, I use plain calcium powder.
