If every plant in the tank is pearling, can the assumption be made that the plants are receiving adequate nutrients (i.e. iron, potassium, et cetera)? Or is it possible that they are still lacking in a nutrient even though they exhibit this "healthly" characteristic?

Found my answer. Apparently, a plant can be deficient in a nutrient and pearl.

The moral of the story:
Pearling ain't everything.

Just wanted to add that pearling simply means that the oxygen saturation of the water has reached 100%. This usually coincides with lots of healthy, growing plants, but there could well be deficiencies lurking.

I have much pearling, almost more pearls then plants...but the plants are NOT healthy, they look pale and shows up a lack of nutrients. Are pearls always O2?

I think it is always O2, but it is possible that it isn't the plant that is pearling, but the green algae that cover it, which then isn't the kind of pearling you'd enjoy too much.

Too much light and too little nutrition can cause those pale plants. Balance is the key... you will need a lot of fertilizer for a tank with a million watts like Knetter's, both macros and micros along with CO2.

Wasser is (as usual) right on. If you put a ton of light over a tank, the plants will quickly use up available CO2 and nutrients due to accelerated growth. If they are pearling, that usually means CO2 is ok, and a lack of Co2 usually won't harm plants...just keeps them from growing as fast, as bushy, etc.
You might start with some root tab fertilizers, like sea chem makes. Then start looking into liquid ferts for the water column...like Flourish.

THANK you Wasserpest!! I was in the dream that my tank has enough CO2 and that the pearls ARE CO2... ops: So you're right about the CO2. Thaks to this topic. I've add 2 extra bottles of (DIY) CO2 2 weeks ago and all my plants are growing again! They creating fresh leaves, the BGA is diminishing and the pearling is not so heavy any more (i think because the cyano :?) Nice for me but hubbahubbahehe still having the problem. Try adding CO2 hubbahubbahehe and you will see...

I am glad that worked out. If you still grow pale plants you need to look into macros... mostly NO3 and K, but if you have algae problems also PO4.
