More Calcium and Nitrogen with Jacks or Masterblend???

I have consistently run into Calcium issues and my plants are never that Dark Green.
I know strains vary in their degree of Greenness.

I also know there are other reasons like temperature humidity and air movement and Other Macro Nutrient Rations that can effect calcium Uptake.

That said please entertain me.

I have read some people using a Jacks 2-2 or 2-2-1 and Loving it. Not sure how many top ups in RDWC I could do before the Nitrogen or Calcium might build up TOO HIGH?
Ironically I just got some Masterblend and it premixes much better but the irony is I got it because I liked the 2-2-1 Formula not that my 250/165/64 (Liter of Water) 1000ml) was anything but a Math calculation...

I think the Masterblend Premixes better because of the lack of Magnesium Sulphate maybe???

Anyway I could make my Master Blend more like a 3-4-1.5 or 2-2.5/1 to achieve this and some Say Masterblend is a little low in N?

Anyone here run Jacks in Veg closer to 3-3-1 or 2-2-1 or whatever. I think my plants need more Calcium.

MY Leaf Surface Temperatures are a little low sometimes 75 ish instead of 80 and cooler at night and in the morning but I am adding back CMH to my LEDS here in VErmont in Winter to see how much my LST is causing Calcium absorbtion issues.

Also sometimes I get lazy and top off my Reservoirs for a week or more instead of changing it out.

Also I am starting to think my 1 tsp per gallon of Potassium Silicate might be throwing off my Numbers K ----- Ca ratio.

I am switching to Mono Silicic Acid.

My PH tends to run a little high in VEG like 6.5-7 but I thought Calcium best absorbs in that range.

I have seen a Chart that suggests otherwise lower PH for Calcium in Hydro...

Any other ideas...

Thanks for your time...

I use masterblend.and i add a little bit of mycos that keeps the ph stable around 6-6.2
