GSA and holes in leaves

[Matty123]

Hello!

I'm seeing holes starting to appear on some of my plant leaves, up to now on my tiger lotus and a stem plant that I can't recall the name of and browning on the edges of the leaves (hopefully I can nip it in the bud, pun indented). Also seeing dark green spot like algae on some plants (there's a bit of the usual bright green spot algae on the front of the glass). I've heard that GSA is due to low Phosphates and tested my tank water and it became apparent that my Phosphates were low at 0.25 and Nitrates between 5-10. I'm a bit stumped as I always 'overdose' with EI dosing and just yesterday overdosed x4 and testing the water again after dosing the results stated above became apparent! Can anybody suggest why they are low even after overdosing and what I could do to improve both the dosing and this dark green spot algae?

Thanks
Matt
