Good advice! I use a 4:1 ratio myself. And 5000K lighting along with 2100K and 2600K.I personally use a 4:1 ratio,most suggest a 3:1
I leave my veg lights(6400k,5000k)on until after the plants stretch is over then I use my flowering lights(3000k,2700k).
If your gonna flower in a few days...just add some 2700k bulbs to what you already have.GL
