Sea of green

I am wondering what some of you may think is the most efficient way to do this method with a hydro set up.The reason I ask is because for instance if I use ebb/flo or whaterver they share the water.So say at week 6 those plants need certain nutes other than say some plants at week 3.I use advanced nutes.for the first weeks you would use big bud,then twords the end overdrive.How do I get around this?I am limited on space.What do you all think?Does this make sense?

hmm having different age plants on the same table you are going to have problems what about putting the younger plants in dirt and having them ontop of something on the table so they dont get the nutes the older one are getting just a thought . Peace
