To early for pre-flowers?

I have 15 feminized Skunk #1 plants from sensi seeds that are in their sixth week of growth from seed. The average height is about 7-8 inches. I noticed today that several are showing pre-flowers. Is this normal for this height? What should I do? I was planning on pruning in a week or two.

Thanks for the input!

Yes, this is normal. Most strains will start to sex around 5-1/2 weeks. This is how you sex plants without flipping to 12/12. Happy growing! (Love that #1 original stank!)

That really depends upon how tall you want the plants to be at harvest. Usually a strain will stretch a certain amount after flower initiation, given in %. I go to strainfinder, and look up grower input into the strain (link below), the first column is stretch. Simple math from there tells you how tall they are likely to be at harvest. Happy growing!

How much longer should I keep them under 18/6 until I switch to 12/12?
