Should be an easy one to figure out for the experts out there, is this the sign of a K deficiency? There's browning and some curling of those leaves too, and its only on the H. Corymbosa. Its not an algae of any kind, its the actual plant. Tank has a coralife dual t5ho, a finnex ray 2, pressurized co2 at 4ish bps, PPS pro ferts and parameters are 0-0-15ish po4 is 2. I started putting in a little seachem K just in case it is that, but I'm really just taking a shot in the dark. Any ideas?
