I have noticed some leaves are 9 lobed and are showing fusion. Is this a genetic or stress related?
Sometimes leaves grow out with a little fusion and is just one of those things. The number of fingers is strain related with sativas having many more than indicas. I've had sativas with 17 fingers and indicas with a max of 5.
I planted 8 fem autos mid June. 4 each of 2 strains and only got one fem auto out of the batch. They were for outside and I wanted 2 of each out there. One strain hi-CBD and the other hi-THC.
5 turned male the 2 left in the garden have 9-fingered leaves like yours and are different strains. Neither have shown sex tho I'm thinking they are female regulars so I'm tarping them over at 9pm and opening up at 9 am to see if I can induce flowering a little early as I'm way up north in Alberta so don't have a long time to grow out regulars here.
I collected pollen from 2 of the CBD boys and used it mixed to dust a branch on the one CBD girl I got today. At least I'll get some regular seeds out of the deal. I'm going to dust another lower branch with the THC male that produced pollen as soon as I collect it tomorrow.
My first try at growing autos outdoors after 20 years of indoors was a dismal failure this year. Hopefully by next spring I'll have better seeds even if I have to make them myself! Will be using STS to make fem seeds of a few strains this winter.
Good luck with yours!
