Any tips for a cal/mag deficiency?

Its my first time using general hydroponics nutrients. I plan on using coco next but for this grow i was finishing up the last of my soil. Any way i started doing the trio(micro, bloom and grow) with calimagic and floralicious at half the recommended dose. I started seeing mg deficiency symptoms so i bumped the calimagic up to about 2/3 the full dose. Since then the mg deficiency has gotten worse and started showing calcium deficiencies as well. I bumped up the calmagic to full dose and nothing got better. Yesterday i flushed the pots each with 1.5 gal of plain ph 6.5 water and then again with 1 gal of nutrient water (585 ppm); everything at half dose but the calmagic which was full dose. Ive also done some foliar spraying with a very light calmag solution in the mornings. I can’t tell for sure but they look like the mg deficiency has progressed even since yesterday. I’m sure someone has experience with general hydroponics so I’m hoping to get ideas on what else i can try.

Age from sprout: 6weeks
Age from flower:n/a

Soil in pots, Hydroponic, or Coco?

How often do I water and how do I determine when to water: every 2-3 days based on how moist the soil feels when i stick a finger in.

PH and ppm of runoff or solution in reservoir?
What is strength of nutrient mix? EC, or TDS.
Around 500-600 ppm

Any other pertinent info:

I checked today and it is definitely getting worse. Idk what to do!

Do you have pics, clear ones in normal light? Up close of leaves and of the full plant?

Are you not measuring pH ?
