New to growing

I got a 240 watt g8led and the plant is about a week old I'm ffof I water with 6.5 PhD water .I got it running on 18/6 I dont what these little white dots are. Anyone help I dont care even it's tough criticism

Grab a jewelers loop and check under leaves for pests. Also how far away is your led

The led light is 24 inches from the top of the seedling and i got a jewlers loop on the way will update

Your light could be too close but I keep mine closer so I doubt that those look like the spots pests eave on plants I use hot pepper spray and peroxide and inscetacidal soap if I end up with bugs or de powder food grade the others may have chemicals ya don’t want in or on your plant

The dots are not a problem.

Be careful not to overfeed.

What's the humidity in the area?
