The soil and perlite vermaculite has turned green...its like a layer of green algea or something...has not effected plants yet...what the hell is it?

The room is in the 70 degree range, however its on a cold floor (the garage downstairs has no heat) The humidity is 40 ish percent.

The soil is a blend of MG and Soilite potting mix...The plants are a month old...a coupe weeks ago I added a small dose of DynaGrow ferts to the gallon of spring water I bought at the store....Same technique Ive always used.

The plants were under 4 43 watt cfl...I just switched them to a 600 MH.

The consistancy of the soil seems wierd on all my plants.

Winter Sucks!

Yup!

You nailed it.
That is algae.
It does no harm, but it means you are wasting light, and perhaps, overwatering.

Indoors, with that little light, you need to cut way back on water because the transpiration rate is much lower and constantly wet feet can kill cannabis.
Suggest you cover the soil surface with a reflective material.
CDs, Paper plates, white sand, paper towels, mylar, whatever.
The algae cant grow without light.
Keeps the fungus Gnats down as well.

As this is your first indoor, and you use spring water, I'd suggest adding Calmag to the water.

You might also want to put a couple 2X4s under your girls.
Gettin' they feet off the cold floor will let 'em transpire more and grow faster.

I feel your pain, brah!
I no do winters anymore.
