You should have been giving it 5ml of calmag per gallon of water since the start, every feeding.

I watched a video the other day saying that some LEDs ppfd is so high that it causes striping Purple striping and people think it's deficient I have been using cal mag since the beginning but I had a lock out issue and flushed down to about 500 ppm I'm wondering if maybe it started showing that calmag deficiency because I had to do a flush mid flower

There's no such thing as a calmag deficiency. If you have too much calcium it can lock out magnesium and vice versa. They work against each other. The reason they bottle them together is that they are two of the most commonly deficient nutrients.
