Welcome aboard…
Enjoy the ride!!
It bugs me that the 
solution is wrong. I don’t want new growers getting the wrong info and ignoring a deficiency.
This is buggin me as well. I thought the same thing My Brother! @Olaf.ILGM can this solution be changed to the right answer?
Thanks. Yeah, one of my seedlings has wild stripes of yellow on her leaves. The plant is otherwise very healthy.
I took out the “solution” tag on my original response to “variegation”. So hopefully, everyone going forward will only find the “cal/mag” answers for Coco leaf spotting. Preshade you.
The pictured one shows it’s lacking Calcium. I know this from the location on plant.
Upper = Ca
Lowers = Mg
Next is how it’s coming in between veins. It’s spotted and not solid. The spotting are areas of high Ca concentrations in the leaf that are being cannibalized.
changed now.

I been Growin almost 8 years and I still have problems diagnosing them. I always get a second opinion from @Budbrother
But looks like you got it! 
I used to the best grower in the world.
Then I had problems with a grow.
Everybody knows more about something than any of us.
Wow, that was deep 
Team, I wanted to post an update.
The original Calcium deficiency never got better, but as planned, once the roots got past the Coco Loco seed block, the Happy Frog soil I used for the 1 gallon transplant provided good nutes. Here is my best girl (Columbian Gold) at 7 weeks from planting.
So happy with this season’s grow so far.
