Week 6
This week started with a lot of cold nights in a row, so a slight discoloration of the top leaves to red/purple is already visible. Could also be the preset discoloration due to the strain's genetics. The Blackberry Kush is growing in a steady pace, with the main stem at its 5th node and the side branches elongating properly. Preflowers are visible, but not abundantly. She could grow a little more, so I will keep an eye on her this week and could maybe add a little bit of N-fertilizer to help her grow a little bit more.
No fertilizer was needed for her as she ends the week with a bushy habitus and a lot of nodes. She will be going into flower next week, with already a lot of pistils showing.
