little white spots on seedlings HELP

Soil PH is also very important. More so at this stage than at any other. If you have to get the liquid test kits. They can be bought for super cheap.
Probably a good idea to remove that light, but how many inches are the lights away from the tops of your plants.
Don't forget to post the information on your soil. Walmart sells alot of seedling starting soils that still have nutes in them!!!! Yep.. just because it says seedling stating soil doesn't mean that it's nute free. I found this out the hard way.
