Hi everyone

Can anyone recognize what kind of deficiency is that , they are 15 days from sprouting ,i found those little white dots on some leafs not all plants just two of 6 , lights on 300-380 PAR LED
Watering with RO water ph 6.5 ,using fertilized soil as they mentioned 4 weeks no beed to add nutrients.

Tent clean no signs of any kind of pests/insects

Also leaf yellowing is normal at this stage or should i use tea or add calmag ?
I had unsuccessful growing experience before ,i just want to do it well , ofc with the help of growers community ❤️
Advices are really important to me.

Those look like bug damage to me. It could also be damage, from water droplets magnifying the light, but those usually look more like brown burns.

I thought also about that ,i mist my plants 2-3 times daily ,i noticed that after i mist once before ,what about the yellow leafs ,normal at this stage or too early to judge ?
 
New growth being lighter in color is pretty normal. But, if you haven't started any feeding yet, and you aren't using soil that is already amended with some nutrients, then you should stat feeding.
