in need of diy cob help

i am new to diy grow lights. i recently purchased MAU5-X Grow Kit 72v, i bought two of them. first one with 3000k with cri 90 and second was 6500k. my plan was to use 6500k for veg and 3000k for flowing, am i wrong on this setup and if so how do i need to change this up? Thank you so much for inspiring me on this diy project. Thank you for all you do
p.s hope i didnt wast my money
