Red Light from Surge Protector Bad for Dark Period

The switch on my power strip glows red. Will this pose a problem for my plants during their dark period?
Also, my seedlings are 3 weeks old and still only have 2 sets of leaves with the 3rd set just popping out, barely. This seems really slow. I made a mistake and gave them nutes when 1 week old. Since then I have flushed the medium (canna, perlite, clay pebbles). They receive 18 hours of 600w MH light at about 2-3 feet away. The growth is almost nothing at all for 2 weeks now. Any opinions on this, please?

Thanks

na the red light wont bother them any. what nutes are you using? any ventilation happening? pics?

the little red indicator light is nothign to worry about....
are you using canna coco?

Canna coco, yes. I used Canna A and B with some squirts of Rhizotonic on two different occasions after the first week. The door of the closet stays wide open all day during the light cycle with an oscillating fan on, and shut with the fan blowing during the dark. They receive distilled water.
I don't have any pics, but tomorrow I will. Oh, and there are 7 Fem White Widow and 2 Fem Auto Flower Little Angel's. The Auto Flowering ones have showed barely any growth in 2 weeks, and are the same height/size as the WW.

dude i thought the same thing today and i had never even thought of that before. im suprised to see this thread. i went ahead and put maskingtape over the light and colored it with a permanent marker. might as well have it pitch black, right?
