These Chinese made 225 LED panels are a joke, despite the claims you'll be lucky if they last 6 months. I'm sorry that you bought them because they are one of the biggest scams in grow lights.
Pure blue is a bad idea except for maybe mother plants. The problem with blue photons is that they will suppress a class of growth hormones called auxins. This is why we use lights with some blue (metal halide) in veg growth- the blue light helps prevent elongation. We need lots of auxin in the flowering stage so we use a light the kicks out very few blue photons (high pressure sodium).

Your 5mm LED arrays are going to perform very poorly, I have 120 watts worth of LEDs, both low power 5mm arrays and high power arrays, and they are a complete joke for growing.
You have a little over 10 square feet of grow area. If your are serious about growing then get a 400 or 600 watt HPS. Your weak LEDs panel simple are not going to give you good growth particularily in the flowering stage. Yes, I know what the manufactuer and seller says, they're full of BS.
