Hey BA
#1 and #2 are 4 days older than #3 and #4. I germinated 2 additional seeds when I lost two due to drowning (my fault). I hadn't used peat pellets before and they were too saturated. So 1 and 2 became seedlings (cotyledon opens) on April 26th, 10 days ago. 3 and 4 opened on April 30th and are 6 days old. Hopefully this provides a better way for you to compare growth.
When creating the
Stage - Seedling: Day in the Header I split the difference to make it easy.
Typically seedlings stage is 2 to 3 weeks so 1 and 2 have 4 to 11 days more in seedling stage. I usually wait until I have three well developed nodes before I change to Veg stage. At that time they will go into 1 gal grow bags until I get 6 nodes.
I think there are a lot of different ways people determine Veg stage. When using nutrients that change in Veg it would be nice to have a standard. Maybe Matthew
@Prescription Blend can comment on when he suggests starting Veg stage therefore changing the nutrient formula and strength.
