Need help with plants

Hi guys I'm having some big problems with my plants. It is as if it is getting small holes and also can not grow ANY moss in my tank. some plants grow good but just don't know what else to do.

-It is a +/- 450 L tank
-2 canister filters running on it
-co2 at +/- 3bps
-Ada aquasoil and a bit of pfs mixed in some places
-dosing EI ferts (NPK and trace)
- 50% water changes each week
-sunsun 6000lph wavemaker for extra flow
-1x odyssea quad
-1x odyssea dual
1x grolux
3x 6500K
1x 8000K
1x 10 000K
All run 7-11am and 5-9pm

My ph was also low and what I've heard is that the water in my area Lyttelton centurion is very hard.
But i added some crushed coral to a net ( about a cup) in the tank to test and be able to take it out. So got the ph up to 6.5.

Some of the plants.





carpet looking good but not 100%


Any help guys
Thanx

 

Hi @quattro,

Pin Holes indicate a deficiency in Potassium. Increase the potassium dosage in your EI mixture.

A noob myself, but this looks like potassium deficiency?

 

Thanx guys.
Was thinking that but just don't want to head in the wrong direction.
Will up it and check what happens

 

Cool man,

 

Stupid question but what fishes do you have in the tank? If you have a SAE, but no algae he/she will eat your moss.
