PS--all the other plants in the aquarium seem fine (many species in this 90g tank--see my journal: http://www.aquaticplantcentral.com/f...journal-5.html)

the unsightly leaves may be toast, but new growth is the concern - going forward if R.mac is happy it will make many attractive shoots and you can remove the other stuff. If you keep P up, it will be more compact and less likely to shoot to the top (internodes will be much shorter).

I've noticed the same thing, when R.mac stunts other plants will chug along just fine but this is attributed to the different requirements between species. Some plants are good indicators of general instability or dosing problems, some are just picky about ranges. The latter usually end up in the 'difficult' category.
