Presumably that would be mg/l or ppm, since 100 dGH is highly unlikely. So 100ppm equates to 5.5 dGH, which is soft. Vallisneria will struggle in this, I know because I keep my tanks at 5 to 6 dGH and Vallisneria does not do well at all. This might be a bit low for the Ludwigia too, being reddish. Redchigh may have more to offer on this plant.
Increasing the GH a tad [with Equilibrium] might see some slightly faster growth. But before going down that road, you might want to increase the Flourish Comp from once to twice weekly, the second dose about 3 days following the first which should be a day after the water change. You could try this for 2-3 weeks and observe any difference. There is calcium, magnesium and potassium in Flourish Comp and although minimal it may be sufficient when combined with the tap water. Also, do 50% volume water changes; the influx of the hard minerals will help.
