I still think that is the cause here are some pics at veg and in flower and you can see the difference both times I grew it it did the same thing( it happend in the 1st 2 weeks of flower) so did the domina cross since then if i see a 3 leaf plant I won't mess with it they seem to auto flower they are harder to clone and are normaly way less potent then a pheno without those traits something to look out for in the future.
