subs super soil entering 12/12 questions

I'm using subcool super soil. I'm getting ready to change from a cfl grow for veg to a 600 Watt hps. Is there anything I Shud give my plants organic wise for the switch to flower. I give them myco and humic acid when watering but no nutes of any kind I know the point is to not have to add nutes but I did have a little n deficiency around week 4 of veg. Also anyone know how far away the hps Shud be from plants. Just have two short bushy Aurora indicas growing.

I have see on the weed nerd that subcool uses super soil and a liquid carbohydrate source like Bud Candy from Advanced Nutrients that has carbohydrates, B vitamins, and amino acids in it

I forgot I posted this LOL. Thanks for the answer my hydro dude uses that and told me about it but I wasn't sure and didn't want to efff up the organic nature of my herbs.
