Just switched to 12/12, should I still use veg nutes??

I've heard about there being N deficiencies in some bloom formulas, and that I should keep feeding veg nutes for the first 2 weeks. Is that true even if the flower nutes have nitrogen? Things I was planning on using for the flower cycle are:


BC Bloom - 1-4-7
BC Boost - 3-0-2
Awesome Blossoms - 2-11-11
Thrive Alive B1 - 1-1-1
Magical - 2-0-0

Did the math and total NPK value is 1.45-1.8-3.3.

Is that enough N or should I still be feeding Veg nutes for now? For the first week?
Here's a picture of my girls, first day under the 400w HPS.

Seriously? No one can help me?

its a Canada thing I guess

Yeah, no one wants to help Canadian girls.

Pretty accurate tbh.

i add a some liquid seaweed and liquid fish when flowering to help with the N def. and it works great and never get any yellowing anymore
