2 led panels 1 300 watts and 600 watts lighthouse hydro

Hi


I would like to receive some advice about my grow room, like I said on the title I have 2 led panels one is blackstar 600 watts from Light House and the other is a 300watts from light house hydro too

I have 6 plants, in 4 plants I pruned for my first time and 2 are regular but they got too taller. Actually the small plants have 20 inches and the taller are 36 inches
My problem is which plants should I keep the 600 watts over?

During my veg the taller plants were receiving light from the 600 watts but now I changed for the 4 shorter plants, I posted some pictures in the last picture it is possible to see the 600 watts under the 300 watts

Should I keep the 600 watts in the Highest place and the 300 watts for the shorter plants? or just keep the 600 watts for the 4 shorter plants and the 300 watts for the 2 taller plants??

ahhhhhh..... they are in the middle of third week of flowering.

Thanks
See ya

Here's my advice man. The plants are way too purple, way too much Nitrogen!
