Help, one plant having troubles -> Discoloration (light yellow-whitish) on some leave

[thesnaggler]

growing in 5gal pots of fox farm happy frog, indoors under 400watt HPS currently 30" above the plants, plants are two weeks old.

problems arising with only white widow (California hash and blue hash have no issues, and everything is being done the same to all three) the two 'hash' plants are probably 1/3 bigger than the white widow, even though all started at the same time

I started off using tap water, which had a ph of around 6. Watered twice, and then just watered yesterday with distilled water. Watering around 4-5days right now.

I have not used any nutes yet (except what came in the soil)

Temps remain between 74-85 and humidity is 38-49%

I have no signs of bugs and I have also looked at leaves though microscope and noticed nothing that couldn't be seen without the scope.

Heres a couple pictures, the only ones that turned out decent:

At that age, especially using seeds, you could just have a mutant plant. Sometimes the genetics just don't cross over the right way, other times it's a fungus. The plant will most likely die after not growing very much. It's just nature, not anything you've done wrong.

It might pull out of it, but if other plants in the same area are growing normally, just give up on it. There is nothing you can do.
