First grow ( DWC hydroponic setup) autoflower*Blue Himalaya*

hello world,this will be my first grow ever!!! before i start the actual grow, i have a few questions.
1. i am trying to use CFL's for the light and run a 20/4 schedule. what kind of cfl light should i buy (watts/spectrum/lumens) and how many will i need****i am only growing one autoflower at a time***
2. for the first 2 weeks as a seedling i am planning on giving the plant little/no nutrients in the resovoir, is this a good idea?

any honest advice is very helpful.

well i really cant say anything about autoflowers but i suggest you get some 40 w cfls and grow some more plants one seems like a little chance to harvest a good amount id do a good 4-8 good luck man ill check back and follow your grow
