Help Repeat weeks on Feeding Schedule

I have a question about repeating weeks in my feeding schedule. I have been using flora 3 series dwc I started at week 2& repeated it now I am on week 3 and plan on repeating week 3. Then I wanted to switch my nutrients to DM Gold add 27 A&B and do 4 mores weeks of veg. Switch to bloom after week 8 then Back to flora 3 series transition to flower and do the same exact thing but as flower. What do you guys think?

I think my head exploded when I read the last couple of sentences. Why would you switch to DM for 4 weeks then back to flora for flower? And then do the same thing during flower? Seems like you greatly increase your chance of burning them up by adding a different line of nutrients halfway into a grow. Seems just unnecessarily overcomplicated. My opinion.
