Whats wrong with my baby?!?!

Temp - 75
Watering cycle - every 4 days
age - 15 days old
nutes - none as of yet
lights - 24 hrs on, 2 cfls and a 400 MH (switched on occasionally, 3 ft away from plant)

Im starting to notice a little yellowing. What can be the cause of this yellowing? check pics below.

Soil type?
pH?

Organic soil with perlite, nothing else.
Soil Ph 6.5

I need some expert advice here, as I dont wanna rush and put matters in my hand lol, Id end up killing my baby

The yellowing is kind of spotty which makes me think it could be Mites... Check the undersides of the leaves for mites and other tiny cannabis rodents.
If you don't see any bugs then it might be time for some magnesium in your plants diet.

There's something in your soil causing your little baby to burn.
the yellow discoloring comes from the active transport of water for chemicals via the plants cells.
Basically, the plant is exposed to too much of one type of element,
and it's tricking itself into thinking it needs the element more than water, so it is causing the cells to absorb too much chemicals and kill the chloroplasts that make the leave green.
The yellow is evidence of dead cells from too much of a chemical in your soil in basic terms.
It looks kind of serious for a plant that young.
I would suggest switching the soil, but that might shock your little girl and kill it.
Weed is pretty persistent for staying alive, you could try doing nothing and see if your plant will get enough growth into it to increase the demand for the chemicals burning it, thus making an equilibrium between the supply of chemicals ( found in your soil at surplus) and the amount it needs to grow.
There's no doubt about it though,
your plant has some chemical burn.

I had something simliar and wasnt quite sure so I got some cal-mag and added it to my water and they greened right up. I also started using super plant tonic (SPT) from blue mountain organics on ebay at the same time so I'm not really sure which one fixed the problem.

cal-mag = calcium & magnesium?
Where can I get it organically, I don t live in the states and online order is out of the question

Well, do you have any large garden centres near you?
That would be an obvious place to look,
but even places like saaaay Walmart...would carry it in the garden centre.
I don't know if it will be organic though.

Is it a store bought brand of soil if so whats the brand.

The soils is Ace Hardware's Organic mix

Im receiving my nutrients in exactly 15 days. Grow Big and Big Bloom from Fox farms.
Was wondering if they will help? Also, will the damage be irreversible in 15 days?


UPDATE PHOTOS

A good source of mag - Banana peels as for calcium try using eggshells itll put lime and calcium in the soil,It worked for my 2ndary nutrients my plant needed.Just make sure to cut up the peels good and small and crush the eggshells nicely as well.Try this if you dont have other options available.

How many egg shells? How many banana peels? Should I add them to water?

Have you ever tried this method, is it reliable?

what fixed my problem like that was a mix of like 5%N soluable, 5%N unsoluable, 8%ca, 4%mg


now they look good

Wow awry, your plants look BEAUTIFUL!!!
Did you have any yellowing occur before it reverted to green?

Could you please be more specific on what you used as nutes/stabilizers?

instead of calmag, go to a garden center and pick up some fine dolomit elime-plenty of cal and mag and also helps stabilize the ph. around 3 euros too.
