Leaves Going Transparent, Anyone Know Why ?

[julioarca]

Some of my larger leaves are turning transparent, anyone know why ?

I do a PMDD system so currently have a Nitrate of 40, phosphate of around 4-5, what might cause this?

Thanks

if they are new plants they could be shedding their old emmersed leaves.
High nitrates & phosphates can cause problems to some plants as can low light or iron levels.
Any idea what plants are losing colour?
