Bleaching/Discoloration/Nute burn? Please Help!

1. Hello fellow farmers! I need some help to diagnose what's going on with me ladies! I have 12 clones vegging in a 3x3x2 DIY grow box with a 24" double T5 and two regular say, 50w cfl 6500k bulbs. The clones are in fox farm happy frog soil and I have only been feeding plain R.O bottled water for the last couple of week.
   
   The problem is that some of the girls are developing bleached leaves and some are getting discoloration, dark marks, and even spots that look like nute burn. Some of the new growth is a super light green, almost yello yellow color.
   I had the T5 about 4" away from the girls and just raised it to about 8 inches. Hoping that works.
   
   Also, I've used FF happy frog in the past for my outdoor grows and I haven't experienced nute burn from the happy frog, but I believe the bag had been sitting for a good while at the hydro shop before I bought it. It is a small bag not the regular 2c.u but the small bag that still says organic on it. I've noticed the newer big bags of happy frog no longer say organic just natural.
   
   Anyways, any help or suggestions needed and greatly appreciated please!!!
   
   Jah bless!

   This one looks like nute burn on the edge of the leaf. Also has some discoloration.
   
   
   
   
   
   
7. • This one is weird it has discoloration but its different than the rest cause it seems like it has darker spots or marks.
   On the third pic you can see a dark mark right above my finger nail.

   The temps in the box average from 75-80 and humidity from 55-70.
   
   I have a small fan inside but no intake or exhaust yet. The lights are on 24/7.
   
   Any other info or questions you have let me know but someone please help soon!
   
   Thank you fellow farmers. God bless.

It's not lock out don't think that direction, your plant is telling you that she's hungry and maybe a tad damp. I hope the pic is readable.View attachment 3600870
