Bluish-green and stunted growth

@ 2 1/2 weeks

@ 3 weeks

Strain: Mendo Purps
Soil: Fox farms ocean forest
Nutes: general organics go box
Temp: 73-82 F
Water: Poland springs

was hoping someone is familiar with these symptoms, the problem could have been caused by a light early feeding at a week+ old (im a new grower and got a lil anxious). Any feedback is greatly appreciated!!

heres same strain at the same age but healthy.
