Default Glosso turns dark and translucent: Calcium deficient?

I have planted Glosso on my 15 gallon tank, gH 3, ph 6.6, temp 26C, nitrate
0 for 3 weeks now. They spread nicely with the addition of CO2 and 70 watt
of fluoroscent light. Just a few days ago, I saw some of my glosso leaves
turning dark and almost translucent. This probably constitutes less than 5%
of all but this is strange as my other plants, Eustralis S., Hemianthus M,
Hottonia are doing well and displaying deep green glow. I use base fertz,
laterite, and Dennerle quartz. I added K fertz from Seachem and
iron/manganese every 3 days...So what gives?

Well NO3= zero, Gloss gtrows very fast, ubnless the nutrients come
from somehwere, it will burn itself out at higher light. You can
reduce the light/increase fish feedings, or add KNO3 or a little of
both.

Gloss will respond first due to it's rapid growth rate so it's your
indicator plant.

Try adding 1/8 teaspoon of KNO3, this will add about 7-8ppm of NO3 per
dose and some K+(enough to not worry about K+ being limited).
Add this 2x a week for now.

Gloss is a very hungery plant at higher light. It does not have as
much storage as the other plants. Well it does, but it'll rob one part
of the mat to feed new growth. Some plants just stop growing when
nutrients run too low.
You may need to add some KH2PO4/Fleet enema also, perhaps a few more
traces(volume, not frequency) roughly 4mls each dose(say if you use
TMG tropica master grow, SeaChem Flourish etc).

Are you in Europe?
