New Grower A few quick newbie questions

[PhxRocker]

Just starting a small outdoor grow and a small indoor DWC grow, using feminized Russian Rocket Fuel & Blue Himalaya Diesel seeds. I'll be using distilled ph'd water for both.

A few quick questions:

I have had some people tell me that I'll definitely need to use a cal/mag supplement (for both the indoor & outdoor grows), and other people tell me that I won't.
Do I need to use cal/mag or not?
And what does a cal/mag deficiency look like?

Also, regarding the indoor dwc grow:

I am gonna be adding supplemental cfl lighting when they get big enough.
Should I use 6500k bulbs during the veg phase and then switch to 2700k for flowering, or should I just use 2700k from the beginning?

Any answers or advice will be greatly appreciated!

To many questions with a lot missing....

1) Hard to answer a few variables left out,
1a)Dwc - what nute base, Cal mag, in dwc you will find you are going to need it for supplement for sure. Not many growers don't in hydro.
1b) OutDoor Soil - Without knowing your soil outdoor plans, hard to even say if needed there. Are you digging out ground and adding in a premium soil or sorts, or using existing? Or a home based soil?

2) Cal mag deficiency looks like a light greenish yellow streak that runs from outer leaf edge in a full wrap all the around the leaf or leaf. Google or faq works there.

3) Not knowing your base lighting, hard to say a thing about your supplemental. If you base lighting is 4 1k's any cfl be a waste if not placed extreme lower part of plant, as an example.
