I’ve got 3 girls going right now…
1 purple have
1 super skunk
1 jack herrer

This is the first time dealing with seeds and seedlings…
More accustomed to clones.
How do I know when my girls are officially in their vegetative state?

When growing from seed they are pretty much in a vegetative state as long as you have them in a Long Light/Short Night light cycle and will show more aggresive vegetative growth after a few true leaves have formed.

If growing from seed, how do you know you have three girls? Are the seeds “feminized”?
