Need some help and direction

Some of my plants don't seem to be doing so well and I'm not sure what I need to add or subtract to get them to grow really nice. Here's a pic of some of the plants

I'd say it's a med-high tech set up with pressurized co2. Lights are on for 6 hours a day and I E.I dose with 50% WC every week. I dose
Kno3 3/4 teaspoon
K2so4 1/4 teaspoon
Kh2po4 1/8 teaspoon
Three times a week and
Micros 3/4 teaspoon
Three times a week
I also use root tabs

Looks like a lawn of BBA on the Anubia's leaves - how much light are they getting??
Can you supply more tank details? Maybe some full tank shots....
Size? pH? KH? NO3? PO4?

They don't get very much light there. It's a 90g tank ph around 6.4 when co2 is on, kh around 8 and the other ones I'm not sure, I do t have test kits for those.

Do you know your GH? Or if you have hard or soft water. That first picture looks like it could possible be a calcium deficiency. Are you dosing any GH booster? I would also try increasing the amount of co2 you are injecting, that is probably the cause of the algae and could be the cause of the distorted leaf growth.

My GH is 9 I'm not sure if my water is hard or soft. I also turned up the co2 more

Macro's seem a bit high? - assuming approx 10g/teaspoon - you are looking at around 12ppm NO3 per KNO3 dose, 2ppm PO4 per dose from the KH2PO4, and around 11ppm K from the three salts...

Have you done any testing to see where levels of NO3/PO4 are??

Ignoring plant uptake (and additions from fish waste) - your NO3 may hover up to about 70ppm with your dosing, and PO4 to 12ppm.... too high IMO, especially if you are having algae problems.....

Try doubling your water changes and half your dosing, and pick up as many test kits as you can, NO3, PO4 and Fe would help the most.

When you give numbers, also include the units. GH is measured in several different units.
If your GH is 9 German degrees of hardness, then a lack of calcium is highly unlikely. If it is 9 ppm or 9 mg/l then a calcium deficiency is very likely.

Test right before a water change, then shortly after. Wait for the new water to get well blended, but before you dose any fertilizer. Maybe an hour or two after a water change.
