Looks like the first of the pistils are starting to pop. I took a lot of pics of this spot and this is the best I could get. Still a little blurry, but you can see the white tip where the pistils are starting to come out.
I took some better pics of the same pre flower from earlier with different angles. Still can’t get a good focus on that tiny spot but it’s better than the last attempt.
Both of the ones that had the more wide Indica type leaf early on. Once they all got older they grew out of that (So did the Sativa looking one) and leaves look pretty much the same. The last male that was removed had heat stress damage and was paler green.
I will be numbering them when they are transplanted and take cuts when they go into flo.
Thanks @AUM I never did much LST in my past grows. Using the bottom four branches from clone or the 2nd and 3rd from seed, top above, tie the branches horizontal and pinch or tuck any fans blocking the shoots.
