Hello everyone - I have been in the hobby for several years but just recently trying my hand at aquascaping and high tech tanks. I think I have gotten my macros and micros at a good levels in my tank but I suspect I’m still having a PO4 deficiency based on seeing dark spots on older leaves. Would love your thoughts to confirm what I suspect. Thank you for your time.
