i think you will be just fine too.

The plants wont even show their sexes for a week or 2 anyway. I got some good advice today which was, don't count the weeks of your bloom from when you change the light cycle, count from when you see the pistils (white hairs). I am using a 190w LED and just 4 x 20w CFL. The CFL are only in the tent to keep the temperature up. The LED light can be switched between light spectrum, bloom (red), veg (white), and both on together. At the start during seedling stage I had only the veg spectrum on for a week or 2. Then I switched to full spectrum (both red and white) and I haven't changed that since.

I am 2 weeks into bloom (since seeing pistils) and I will leave the full spectrum on until the final 3 weeks or so of bloom. Then I will just let the red spectrum run with the 4 x 20w, 2700k CFLs. So to answer your question, I think it's good to have some blue mixed in with the red spectrum during bloom, but you dont have to, thats just my preference but it doesnt hurt.. I could get a 1000w sodium vapour off a friend if I wanted to boost the bloom but I want to test the LED light so I can see what results it can bring. So far it's looking great.
