End of flower ratio for Jacks 321

In veg I use The normal Jacks 3.6/2.4/1.2 ratio. Then in early flower I use 3.8/2.2/1.1. Late flower 4/2/1.

My question is: Would it be even better to change the end flower to 4/1.5/1.2?

Based on the idea that in flower especially the end, the plant needs less nitrogen, more phosphorus, potassium, magnesium and sulfur.

Anyone tried it before or have any thoughts on it? I want to push and get the most from the plant without pushing too far.
4/2/1 works very well but was thinking maybe 4/1.5/1.2 would work even better.

If you drop the calnit, you are dropping calcium along with nitrogen. Might need to drop the epsom to keep the calcium/magnesium levels balanced. 4/2/1 has worked well for me from 2nd week after flip til harvest.
