Seedling Problem - Yellow Spots

About one week old. 500w / 20+" away. 26degreesC / 78.7degreesF.
Promix. Not nutrients fed yed.

Was going to start with a very low dose now? Bud I'd like to conclude what this is exactly before throwing anything in there .

Calcium deficient?

Anyone?

Doesn't need any nutes at that stage. Looks like you spilled some water or w/e on it.

pro mix as no nutrients at all ,if you have something like clonetek that is what i would use ,what type nutrients do you plan on using ,right now would be a good idea at a very low dose,maybe at 1/8 strength per gallon with 1/2 teaspoon epsom salt ,keep your ppm under 200 .if nothing else i would do 1/2 teaspoon epsom salt 1/2 teaspoon molassess ,per gallon that would be nitrogen an calcium and mag

Could have got misted slightly when misting another cup that hasn't yet sprouted?
Gh lucas. started at very low dose. Should I start molasses now as well or wait until later?

oh my
