Having a problem identifying the problem

Hash plant
Pro mix potting mix soil plus some perlite
t5 lighting until my diamond series 200w led arrives.
Just tap water
just started a few days ago with dyna grow foilage.

Have seen this weird bleaching look on the majority of leaves since a week old.
Moved light further away (6 inches) didnt think that was the problem as the light is not that strong.
Hoping its not a pest problem but doesnt look like any pics I have seen of pests or deficiencies.

Any ideas would be great. will be getting a ph tester for my tap water asap.

Not the best chart to go by... It could be a deficiency or even an abundance of something...
I know another site that has better pics of messed up plants.... hold one...

I'm seeing a nutrient problem, not light....

yes i took a long look at that picture and spent a day on google looking at every picture i could find but none looked like mine. some leaves looked perfect on one side of a blade on a leaf and the other side looked healthy green. I figured deficiency or over abundance would be some what evenly spread on a problem leaf.

Thanks for the response

This one give a little different look...

hmmmm
still unsure. thanks for the pics though. sort of looks like between mag and phosph. in the first pic looks like nitrogen abundence.
hoping someone has seen this before and knows exactly how to correct the issue.
have a couple more seedlings on the way and wondering if i should use different soil and or water.

Well your not alone just my dwc sour diesel has that in veg think growing to fast fills in in time this plant start of week 7 this one 2 weeks had spider mite just check my ph 6.1 they both are do for res. change

well that is quite the chart wiethe20. this will stay with me and aid me I am sure.
The noob in me has still not been able to narrow it down.

The closest thing to "uneven light spots" I see might be interveinal chlorosis.
Think I will try one seedling with different soil and one with different water and see if the problem persists.

SPIDER MITES! geez that would be worst case scenario for me. spiders of any kind creep me out lol.
Not sure if our leaves look the same Terry.

Thank you both for the help.
Any more feedback is welcome
