I am no expert, but from reading the threads on here you do not have near enough light. you would get 3000 lumens just from 1 40w flouro.
You are going to need more hight (23" will not cut it) even with just flouro tubes you have 3-4" for the light and probably at least 6" for the pots that only leaves you with 13" for total plant growth. And the flouros won't cut it for flowering (not the amount of them you are using). And you will need to vent your cabinet.
