Landens aqua soil and ph

Hello,

This is regarding a caridina shrimp tank that’s been prepping the last 45 days or so. I use RO water remineralized with:
Mgso4 : 10ppm
Caso4.7: 20ppm
KCL: 10ppm
TDS 130~
Nitrates sit at about 5ppm. Moderately planted.

PH 5.2-5.3 (freshly calibrated ph pen)
Any thoughts why the ph is so low? I was expecting more around the lines of 6.5. Should I add in some carbonates to get maybe a 1kh?

The crystals going in are raised in about 6.4ph from SoShrimp. The Gourami in the tank now seems to be loving life. Im curious for some thoughts because I know most reminerlizers are just mgso4, caso4, k2so4 so I don’t get why my ph is so low.
