Unusually pale seedlings in soil!?

Hello Rollitupers,

I have been growing for quite a while now but I have never had that problem before.

I am growing an Afghan strain in a store-bought organic soil.
The temps are between 62f at night and 72 during the day.
The humidity is around 65%.
I have been watering with straight water at a PH of 6.3
The soil is allowed to dry between waterings.

The plants where growing under a 60w LED and they have been under a 600w HPS for the past 24h.

Here is my problem: The seedlings are all very pale and the growth is a bit slower than usual (The plants are 9 days-old but look like they are 6 days-old). The stems also look a bit purple.

My question: Are the plants suffering from a deficiency or a nutrient lock-out? :???: I'm using an organic potting soil I have never used before and I don't know whether it is too rich/hot or too poor. The texture is very good tho (Not too dense with perlite and shells).

If you guys know what it is, I would truly appreciate your help.:wall:

Hi Hotrodarley,

The leds were pretty close at about 3-4 inches but it was only a 60w. The HPS is at 30 inches with a light mover.

Also I transplanted yesterday, they were in a seedling tray before that.
