when should I start to flush?

I'm growing some bag seed herb and I don't know how long the flowering period is. I'm now just passed week 5 and there is quite a lot of Thc chrystals as well as some hairs have started to turn brown(not a lot of hairs but some none the less). I'm giving her nutes and molasses. I'm pretty sure molasses doesn't need to be flushed right? I can use it till harvest if I wanted?
But yeh any ideas? Week 6 is only a few days away. Though I still feel as if the buds haven't done their final swelling yet, maybe it could be a 9-10 week flowering time? It doesn't look to be fully sativa but leaves are dwfinyely longer and thinner..

just go buy the trichs. if u want them cloudy, amber then start ur flush. you can use mollasses to flush with also..

ty!
Anyone else have any input?

I heard to flush during the last 2 weeks, and i have used mollasses before and would would reccommend it. about a tablespoon per gallon maybe a little less

Absolutely has nothing to do with my post bmasta lmao!

Almost all strains need at least 9 weeks in flower before harvest. Be patient, far more growers harvest too early than too late.

good advice! I was thinking they may need 9 weeks because of the sativa in it but wanted to hear it from someone else for confirmation.
Just started a indica dominant strain with some big fat leaves on it so hope it'll e a female cause I haven't grown anything with leaves this fat lol.
