Adding fertilizers only makes sense if you have enough light and CO2
, otherwise the plants won't be able to use them efficiently & you'll just end up feeding the algae (or if you use RO
water). The plants you have are all low light, slow growers that don't typically require fertilizers. For the time being I wouldn't dose anything, at least not until you get the algae completely under control. Watch how the plants grow on their own, and if you notice symptoms of deficiencies you can then add the appropriate fertilizer and build from there. All-in-one ferts like Thrive don't always work, as they have a fixed amount of nutrients and you can't really adjust the individual components to suit the needs of your particular tank.
Basically it all depends on how many animals you have in the tank and the contents of your tap water. Your algae bloom was probably due to the fact that you added macronutrients (nitrogen, phosphorus) to a tank that already has animals and probably had enough macros to start with. The plants' metabolism was too slow to absorb them all, and the algae started growing instead.
Don't sweat it, it's perfectly possible to grow these plants without any fertilizers at all. You just have to observe them and see how they do.
