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.
