New Grower Seedling issues

[blood12]

Hello,
This is my first grow, and currently growing 2 hijack and 1 northern light blue.
Right now I am having issues with 1 hijack and the northern light blue.

Northern light blue
As you can see in the image below some lesions are appearing on the leaves



Hijack
This one is really weird the leaves twisted down and growing like that



Both are 6 days old.

I am using a 250 w MH lamp, 2 feet far from the seedlings, heat is not an issue since There is a good ventilation.

Today in the morning I watered both of them.

The soil I am using comes with enough nutrients inside it.

The only thing I can think about right now is the ph of the soil, and ph of the water I am using, my ph meter is displaying 6.5 but I cant really trust it, its not very reliable.

Please if somebody got any suggestion of why this is happening let me know.

Interesting strains you have there :High 5:

without a temp reading, don't be so sure heat is not your culprit. I'm going to guess its possible heat stress or more likely your soil has too many nutes it making it too "hot" for those precious seedlings.

I would: 1. get thermometer of some sort, preferably one with a humidity reading also. If that's not the problem, flush that soil unless there are time-released nutes in there.

Does flashing the soil at the time cause damage to the seedlings ?

What do you mean by "flashing the soil"
