About two months ago I got some ludwigia peruensis
from Steve Maier. It was stunning - a nice deep purple!
It grew fine for about a week or so and then new leaves
started getting this slight crinkle to them and growth
got REALLY compact. It's hanging in there, but not doing
well at all. Then about two weeks ago I got some more
from someone else - and again - got a dozen new leaves
and then the same thing is starting to happen.
I'm starting to think theres something Im missing
nutrient wise. I think the plant has a little bit
of 'stored' mystery nutrient and when that runs out
it starts giving me this weird growth.
220 Watts CF
50% water changes weekly
1.5 tsp K2SO4 weekly
Nitrates from fish at around 5 ppm
Try to keep PO4 at 0.5 - 1.0
Traces from the mix at hydroponics.com
A little crushed coral in the filter
pH 6.6 or was it 6.8 - don't remember.
