Brownish yellow spots. Help please!

I noticed these little brownish yellow spots on multiple of my plants today. Started from seed about 2 weeks ago, Ocean Forest and Happy Frog mix. Under HLG 100 using BioCanna Vega and Rhizotonic and following their personalized feeding. PH water after bytes around 6.3-6.5. I’ve had temps at around 80* and 60% humidity.. Any guesses what it could be? Any and all help is appreciated! There are pics with my phone flash on and off, no LED on.

Thank you!

Your soil has enough nutrients to last several weeks your plant is to small to be adding nutrients. Ease back and I would recommend running a 1/4-1/2 recommended dosage until there completely mature.

This. I was old to wait at least a month after transplant before using nutes in FFOF and when you do go 1/4 on a water, water, feed schedule and the same schedule for flowering. You can up it to 1/2 after a few weeks.
