Is tghis the API GH kit, or the Sera? I've not used the Sera; the colours on my API GH kit are orange to green, and it took me a while to fathom the changes.
GH is at 3 dGH or close, so that is very soft. Looking at your fish list, this is perfect for the soft water fish which is everything except the platy, they will struggle. I would either return these, or separate them into another tank and increase the GH for them.
Plants should be fine, though 4 dGH is usually mentioned as the minimum. This is due to calcium, essential to plants. But rather than fuss over this now, I would leave the GH and see how things go. If the plants start to show signs of calcium deficiency, we can discuss options.
