BioThrive and BioRoot are amendments, not necessarily fertilizers. Somebody isn't paying attention to the bottle's contents. What you need to do is give an NPK ratio and you can do this with BioGrow if you want. I usually recommend Dynagro fert, however, as it has most of the micronutes plants need. There's nothing wrong with what has been given, but a shot of nitrogen will cause those plants to green up. What that happens, consider growing them for a longer period, to recover and produce more. I'd get the Dynagro because your plant is showing yellowing at the top, which means you're missing a particular micronute. Dynagro fert will supply this. Read the back and you'll see that for a soil grow, you use 1/4 to 1/2 teaspoon per gallon of water. You can continue using R/O if you want, but in my opinion it is better to go to the store and get bottles of distilled water as R/O has some salt to it. Only water when the top inch of soil goes dry.
Dyna-Gro You shouldn't need anything else.
