Are you pHing your feedings? If you come back reply to my question by quoting my post so I know you have responded.

Ok, to me the browns spot look like a slight Magnesium deficiency. Maybe try giving this one a slight boost of Cal/Mag next feeding? Have you used any Cal/Mag in this grow at all? The good news that if your other plants are healthy, than its likely nothing terrible is wrong and this is likely just a matter of tweeking your feedings for this specific plant.
Southerner:
Yes i am adding 5ml of calimagic per gallon each time i feed or water them.
Here are some pictures from last night of the some of the other ones.
Im going to feed them more today!
Thank you!!

that's a lot of cal-mag for those seeding,dont believe every thing u here what u growing in? soil-coco
Coco coir and perlite 50/50
Currently
Per gallon:
1/2 teaspoon (2.5ml) floramicro
1/2 teaspoon floragro
1/8 teaspoon (0.5 ml) florabloom
Per gallon.
1 teaspoon of cali-magic
Using R.O. water.
Use pure R.O. water plus the calimagic every other feeding.
Right now they are about 18 days from seed.
Thank you

Sorry i meant 16 days from seed not 18. So they are about 13 days since they sprouted.

2ml micro/4ml bloom per gallon.
all you need. Just keep that 1:2 ratio all the way to the end, increase total nutrient load as the plant grows all the way to 8/16
add your calimagic in moderation in coco... dont really need more than a couple ml per gallon and not every feeding.

Did you drip water on it and are you using LEDs? Because it's either that or look for bugs on the underside of your leaves.

Pretty sure they're bug bites. Second idea is water droplets plus lighting (usually LEDs).
Hi Olive Drab,
Yes I am using these LED (see picture)
And I checked I dont see any bugs in the plant.
I have been careful to dry the leaves whenever nutrients/water gets on it..but its possible it could be that not sure.

I think you may have dripped a little on them with your light too close. Not 100%, but I don't think that's Mg. Not totally sure, though.

Doesn't even necessarily have to be too close. Water acts as a magnifying glass and the leaf directly under it is the ant.
Listen to this ^^^^^^^^^ and get a good picture of the white spots on the underside of those leaves. If you can't get a macro image then get a magnifying glass and look under those leaves for movement, webs, bug feces.
I grow in 50/50 coco/perlite. I feed the same nutes. I'd drop the pH a little more. I try to stay 5.5 to 5.8 but will allow drift to 6.2. Hope this helps. I don't see any deficiencies. I hope it's just a bit of light burn and not bugs.
PS I use tap water (no chloramines), and my tap has a TDS of approx 250.
I was able to take these images of the underside of the leaves of the plant in question...

At this point just watch it and see what develops. If it's bugs you'll know soon, watch it closely. With lower leaves it could be water splashing up.
