i plan on making a reef tank my tank is cycling now in its 3rd week. what would a normal and suggested reading be? calcium too sorry

I would just ignore the phosphate level at this point. The decay process can throw off a lot of nutrients. For calcium, 350-450 ppm is the recommended zone, but it's not critical at this point.

oh ok when would it be good to start testing for it?

Would you not want a zero reading on phosphate.

Zero reading is always best but Bertoni is saying that it is not important at this point. It will be important later on. While cycling it doesnt matter.

Yes, just focus on the Ammonia, Nitrite, and Nitrate trends until the they read 0, 0, and minimum 20 respectively. I recommend all three being at zero, it doesn't take much longer to drop nitrates. After that, I would do a water change to even out various chemicals that may or may not be testable, and then start worrying about pH, Calcium, Alkalinity, Magnesium, and Phosphate.
