What week of flower is this? (strain: black rose early)

Rough guess would be about 6 weeks, half way there.

 

I agree, its almost there. Day 42-56.

 

Hard to impossible to tell, depend on the strains, some strains would take 9 weeks to be at this stage, some 5. I'd say about 3 weeks left, might be early choppable in 2. Pistills have not even started to turn brown. Looks nice and healthy! Nice job!
