Stonerdanswered grow question 4 years ago One of the more common cannabis mutations!
To answer your question yes this is totally normal and even might be an indication for a healthy plant!
If there is damage to the foliage that shows signs of stress then it is probably an inherited genetic mutation!
Any way leaves with 7+ leaflets aren't anything to worry about and if you want to check out a plant with that mutation I have a flowering plant right now Named "Unknown #2", she is growing beautifully and vigorously.
Hope this helps! Good luck and happy growing :)
