riccia not pearling

I have a nice lawn off riccia growing in my tank which is lovely and healthy, but i read off peoples riccia pearling why doesnt mine, apart from that it is growing nicely.
kh 3-4 degrees
ph 7.2-7.4
nitrites 0
nitrates0
phosphates0

i am running bottle off co2 which is always at its optimum level, i have fertileser substrate, under gravel heating , 5 dennerle 42 inch t8 tubes and add weekly ferts and also do a 25% water change every 2 weeks.

What else can i do!!

Get your Nitrates up to 10 ppm and your Phosphates to 0.5 ppm, weekly water change of 40 to 50% is better than every two weeks.

I didn't start getting regular pearling in my tank until I switched from DIY CO2 to pressurized and got my CO2 levels >20 ppm. Also, my current 'regular' pearling is usually noticeable in the evenings when I get home from work, but not in the mornings when the light turns on.

Hello Danny
For NitrAtes use Potassium Nitrate KNO3, and for Phosphates use Mono Potassium Phosphate KH2PO4, or Fleet enema...
I'm not sure if greg ships to the UK, I have sent him and email asking him just that, so will know soon. with a plant tank you want a target range of 10:1 ratio Nitrate to Phosphate.

Got an e-mail back from Greg:
>>Hello Greg Couple of questions
1) Do you ship to the UK?

Yes I have setup a mirror site at http://www.PMDDStore.com which ships via the Post Office for all international shipments

So you can get all your Nutrients shipped to your door
