Hello guys. I’m doing some research with my plants. Have one plant which started to flower 10 days sooner at her 18 days comparing to her older sisters (34 days now). All plants green poison auto xl in soil. Older have been put at balcony from beginning and started to flower at their 28 day both. Genetics very variable as one plant low and bushy and other tall with narrow leaves. Can happen with hybrid though.
The younger started with help of flc bulp from sunset to midnight. I’ve stopped to give additional light 4 days ago. She was 9 days ahead with nodes, compared to her older sisters. Actually her older sisters have started to show pistols as well when second pair of 7 point leaves were out. They were much bigger with other colas developed due to age.
What is it? Change of light or the plants is programmed to show pistils when second pair of 7-leaves out?
