So I'll have to try different ones while watering along with my aquarium water and learn by mistake! I'll get three fertilisers with a different number highest each and try them throughout the year.
The tank water will have, in a week, added fertiliser and co2 booster for the aquarium plants I recently purchased.(by API)
Hopefully that helps them too. Can I use the magnesium on all my houseplants?
Got the regular, Crassula Ovata, Kalanchoe, Aloe Vera, Ceropegia Woodii and a Crassula hybrid of some sort.
