Are my Autoflower’s small for their age? Could they be stunted already? I planted the germinated seeds in their final 5 gal Smart Pots. They are each a different strain. The 2 biggest plants popped out of the soil on June 1st. The other 2, about 3 to 4 days later. They all seem smaller (especially the the 2 that popped later) than they should be at 18-22 days old.
