Chris, i assume you are EI dosing. if you are, don't even bother with trying to figure out a dosing schedule for your terrarium plants. just water with tank water from your planted tank. the whole point of ei dosing is to over saturate the water column with more nutrients than the plants could possibly use, which you dilute weekly with water changes. at the end of a dosing week, just fill your spray bottle up with all the nutrient rich water. that's what i did when i had my planted tanks ruinning and was ei dosing. the plants love it, especially marginals.
