Unsure what is on my driftwood and now on some of my vallisneria

I have this sort of white stuff that has started to spread on my vallisneria and on my driftwood. I have not seen this before in my years in the hobby and i can't find answers anywhere so hopefully someone can help identify it. It spreads on the vals and eventually the leaves seem to die. I am dosing an all in one fert and all my water chemistry is completely fine.
I have attached some photos

Do you have PH, GH, KH readings along with ammonia, nitrite, nitrate and phosphate readings?

Full tank picture showing substrate side profile and planting density?

amonia 0ppm
nitrite 0ppm
nitrate 0ppm
I know my nitrates are low for plants but they never really go up in the tank even though it has a decent stocking. maybe it has something to do with super low nitrates
I dont have ph,gh and kh tests left but will order some soon
Substrate is about 2 inches deep and even 3 inches in areas at the back
The vals have spread densley on their own at the back of the tank, the used to fill the tank but i removed some as i want some different plants at the front.
Substrate is gravel with root tabs and liquid ferts
they have been growing and propagating fine but this stuff on some leafs is a new thing.
Here are some pics of the tank

Looks like a couple forms of diatoms. Usually caused from a nutrient imbalance.

Anyway get a phosphate test kit also. Need that reading as well as others. Are you making sure to violently shake the nitrate reagents for 2 min before running test? If not it will always read zero. With amount of Fish there I find zero nitrates highly suspicious.

What liquid fert and how much and how often?
