First of all, I don't KNOW shit! So having said that, what I think would happen is that the babies would be photo period due to the fact that the cross to make an auto flowering plant is occomplished by introducing a small amount of The auto flower plant (forget the name) into the primary plant. Second time around that gets watered down more and is lost for all intents and purposes. Thereby reverting back into photo period. Having said that, MJ is in my opinion at least, not true to seed and therefore it is always a crapshoot unless you are dealing with clones. This opinion is based on my vast experience (one successful grow) of planting six LA Confidential seeds from Budda Seeds and getting at least two very distinctly different plants. More accurately it was LA Confidential X OG Kush so it may be that one plant leaned towards the mother and one to the father IDK but I ended up with at least two if not three distinctly diff plants. On a good note all the plants were robust and potent.
