mixing GLA EI package

Hello I have a 55 gallon tank using pressurized co2 with a diffuser.
soil is dirt capped with gravel

I notice lately my plants arent doing so well after about 4 months now, they were growing well before, now not so much. I notice a little bit of BBA starting to crop up on the end of some leaves.

I bought the GLA Estimative Index package. I have a scale, I've been trying to get things right on those nurtient calc's. trying to calculate for a 500ml solution.

Calculator comes up with:
159g Plantex CSM + B/500ml @ 5ml every 2 - 4 days
254g KNO3/500ml @ 5ml every 2 - 4 days
39g KH2P04/500ml @ 5ml every 2 - 4 days

I have hard water so I haven't calculated for K2SO4

does this look correct?

If not, can you please guide me in the right direction?

I do 40-50% water changes every week.

Thanks.

Looks good to me. Don't forget the weekly water change and you should be all set.

Dry dosing seems much easier and that's what I do with my EI fert pack. At 5:30am it's much easier for me to open the weekly pill sorter to what day it is and just dump it in the tank rather than fumble around with measuring out a liquid mix.

can I combine the KNO3 and KH2P04 into 1 solution?

Yes, but it's more versatile if you don't IMO. Just don't mix KH2PO4 with Plantex. The phosphate and iron can bind if you do.
