Lemon Haze

Update Day 4 : I noticed she started to stretch so i decrease the light distance. Day 7: Question comments section I noticed yellow spots on the surface of leaves, i dont think thats sign of a deficiency coz it is impossible at this early stage with my soil (biobizz with 1.1 Ec), seems there is pests so i placed a yellow trap lets see what we catch. Guys Please let me know if im wrong or it is about a deficiency. Day 8 update : After setting up a yellow trap i have catched two black flys but i dont think the yellow spots are for flys or pests bcz i put a cap on the seedling to provide suitable humidity for seedling, so i asked in question comments n have got couple of answers from guru and masters that it is not a big deal, n it might be a light burn of spilled water on leaves and they were right.
