Is this water/light burn?

This one was planted as a seed 10.5 days ago... sprouted after 5 days. There is another one in a pot right next to it that an identical issue, but it is smaller by a few days so it doesn't show as well in a picture.

First time grower:

• Platinum p150 on veg, 8-10 inches away. Main leaves starting to leave the cotyledons behind.
• Two of the following three strains are planted: Think different, smokin gun, cheese candy - all fem auto. I did not keep track of which strains were planted where (I know) so the one I'm showing here is one of those three.
• Fox Farms Ocean Forest + 20% perlite
• I overpotted straight into a five gallon. Been watering every 3-4 days, a small amount for the pot size (less than 1/3 gallon), directed primarily in the plant's vicinity. Trying to pH around 6-6.3.
• Adding tiny (less than 30% strength): Oilycann (Cal & Mag), Superthrive, and Fasilitor to every other watering. This could be my problem, tap water is 250 ppm before any nutes.
• Grow tent, I can go into more details about this if it matters.

This could realistically be a pH issue (getting a legit meter tomorrow) or my water is too heavy (Using Brita for now, brings me down to 150 ppm and reduces pH enough). Hopefully, though, they're just spots that got burnt... I sprayed them and they sat in the light yesterday. It could also be oil from my fingers (tried to brush off the water after I realized my mistake).

The attached picture is the best picture I have from two days ago, the leaf seems much more healthy back then... which backs up my burn theory.

I would greatly appreciate some more experiences eyes confirming this, thanks.

that looks ok to me

never heard of platinum p150 what is that ? a type of light? it looks ok to me as well but i wouldnt have started off with such a large pot..i guess u mean the little dots ? this could have been a problem already in your seed or maybe a little splashing on it if youve wattered and then the light hitting it? i wouldnt worry about it she looks good and healthy.

Looks like a wet environment with direct light or excessive heat exposed to the plant at some point

I appreciate the quick responses guys, glad to see that I might be overreacting.

Platinum p150 is an LED continuous spectrum light. There's a discussion somewhere here about their somewhat shady advertisement practices, but (so far) I've been happy with it... we'll see when I get to flowering.

On the "wet environment" - that makes sense. Relative humidity is 60% at 70F, not to mention the water spraying I mentioned above. I had heard that higher humidity is good for the early stages, but do you think it's time to start up the dehumidifier?

Your absolutely right about more humidity in the early stage then of course your guna drop your percentage as the plant matures .....the plant is still young so higher humid levels aren't guna hurt anything just watch the heat from your lights so you don't burn your baby .....as far as firing up your dehumidifier your just guna have to check things with your meter and go from there Just remember don't over think things and keep your environment comfortable for your girls and they should be just fine ....there's lots of good info on humidity levels for the different phases of you plants life Good luck happy growing

didnt see about the water spraying... that is the problem/... woter beads magnify light,,,, u should only spray when ur turning ur lights off or atleast move lights away

also u shouldnt be using superthrive every feeding if thats what u meant.... and definitley not at flowering ...superthrive should at the most be used when your plants sick or going thru transplant shock, its not an supplement u want to use for a normal feeding imo.
