Having done a bit of research, I think that my plants don't have enough Iron?
So I have started to delve into water chemistry!!!
I know it is probably over the top to go this complex, but I enjoy learning still.
The leaves seem to be going yellow at the edges.
Did a bit of calculations and came up with these ppm values for the tank water
Are my calculations right?
Are those recommended ppm about right for a low tech tank?
Do I need to put extra of anything in?
Seems that table has corrupted, will look later to see what is wrong.
