In need of somebody with Kush growing experience

So i was wondering if anybody here had any hands on experience growing kush in a flood system. I'm growing Pre-98 Bubba and OG Kush Abusive, both in seperate flood trays, one week into flower. My question is if flooding them out of the same resevoir/nutrients solution would be appropriate or harmful. I currently have them set up to two seperate resevoir which I in which i put equal nutrient solutions.

I'm having great results. Just trying to simplify the settup.
