2nd grow, 5 plants, aeroponic system

I joined a couple months ago and never said Hi lol. I've used the information from here for my first hydroponics grow which ended with a male plant, I was using bubbleponics system in a 5gl bucket. I got every answer I needed from reading the posts on here and with help from the search button lol.

I have 4 bag seed plants growing, 2 of them show a bit of purple so I have my hopes
They are vegging on 18/6 and at the end of the week I will be replacing the water in the container later this week . I decided to go with GH for nut's and I am using the GH Calculator so my numbers look like this

Gh floraGro 2.9
Gh floraMicro 1.4
Gh floraBloom 1.4

I am using a shot glass to measure out right now so these are in ounces/32L ( half the container)

let me know what you think.

As it stands now:

Lighting:
4- 45W CFL Bulbs
4- 35W CFL Bulbs
Mylar on walls
I am almost done my new light fixtures, in the picture you will see my 34w bulbs in the one, that was just for testing.

My Plants

looks great....but i see a few things.....one if u r in veg never turn the lights off keep them on 24/7 u r useing cfls so i def would keep them on around the clock....also i see u have some spot on your plants this might be a difficiency to me your res water looks a little dark and that means alot of micro....so u might be borning the little babies....

do u have a ppm meter? at the size u have those plants u should have the ppms over 200-250.....that might be a problem.....or u could actually drain that rez and use just plain water to get better root mass of which i would do.....and if u do get a female out of the 4 keep one for a mom.....gl.....
