First grow, about to flower

Just want to make sure I get it right.

I'am using GH 3 nutes. Do I just go straight to 1-2-3, been doing 3-2-1?

I've got 3 vegged for 4 weeks(about 17''-18'' high) and 3 for about 2 weeks.

I can move my 3 flowering plants from the light closet to the room and the other side of the bed to try and get it as dark as possible. There is a little light seepage from around my closet door, will this be ok? I don't think it would be any brighter than moonlight.

Would this work?

This way I could keep my 3 little ones under a 18/6 schedule.

Thanks

as for what i've read its not the brightness of the moon, its the spectrum of color the moon emmits.. and the marijuana plant does not recognize it as it does other spectrums like your grow light emmits..i'm no scientist, but i read that on here for someone who seemed liked they knew what they were talking about.

Better if you can find a completely dark area for them. As for the nutes, you want a 1-3-2 for flowering. Yes, you can switch right to it, but keep using your veg nutes also, at half or quarter strength, depending on what you have. This will give them Nitrogen needed still, so your fan leaves stay healthy and green.

whats the best nute to give them while they are flowering, right now i am in the veg stage but am about ready to go into flowering

The best nute, is debatable - there are sooo many out there. I use Jack's Classic myself, All Purpose (20-20-20) all the way through, with Blossom Booster (10-30-20) added during flowering. It's a lot cheaper than some of the more popular nutes, and works well.
