I've attached the photo of the loss leaves from my tank. What is the nutrient deficiencies that you think?

Look like posstasium deficiencies.

Looks like several deficiencies in addition to the ones mentioned above. Are you getting Black Brush Algae in your tank too?

The pin holes mean that could be it but it also looks like mottled leaves which is a nitrogen deficiency. What type of fertilizer regime do you have?

My tank is 75Gal, 24" deep, completed with 6x39W T5 HO light. CO2 @ 30 ppm

I started dry fertilizer about a month with dosing as below:

1. Im dosing 5ml daily of Macro Micro Nutrient (MMN) Mix bought from aquariumFertilizer. The MMN formula included KNO3, K2SO4, MgSO4 and CSM+B. I mixed 1/4 cup of MMN with 500ml of water.

2. I'm also dosing 5ml of KH2PO4 every second day. I mixed 25g of KH2PO4 in 500ml of water.

3. 30% Water change every week.

Remove as much BBA as you can manually, trim of the leafs that have a lot on them. Especially if leafs don't look healthy. Spot treat the BBA with Excel or Hydrogen peroxide, with all water flow turned off. Should be able to find a video on You tube.

I subscribe to the theory that if you can get your plants growing good your algae will go away. Fast growing stem plants will out compete algae, lots of water flow, weekly water changes, and proper fertilization all help. Consistency is HUGE, lights and CO2 on timers,water change on the same day, dose ferts exactly as planed around the same time everyday.

Deficiencies can be hard to pin point, but the BBA leads me to believe your tank might need a bit more Phosphate. If you have been constant with all the things I mentioned above you could try increase your KH2PO4 a bit.
