Hi.
I've looked at wk 5 & 6.. those tops that's officially pre flowers mate. You should start to see hairs popping like mad up and down your nodes. Also i see your tops they'll start throwing out hairs shortly. You had your pre Pre flower stretch, usually happens (spurts of rapid growth) along with your tops are signs as the Stigmata.
Daily checks should be bracts. You know the little balls with hairs check her for male pollen sacs. As all ppl should with any strain. As if they pop before pre flower is over your tent will be full of seeds. Your plants I mean. So, a single ball you will start seeing at and under bud sites. Just look up bracts if you see many balls that's a hermie it is rare. But, not as much as it should be. So, its just good practice to look out for all plants that are entering pre flower and thru keep an 👁️ out
Good Growing
