Estimate how long til harvest

I have completely lost track of time.

Can you cast your experienced eyes on the following and give me an estimate. I have no microscope. I think we are in week 7 or 8 of flower. Maybe 50% orange pistils but no brown i dont think. Wondering whether to start the flush.

Apologies thaf HPS went too orange in the last two.

Thanks in advance

looks like 3 or 4 more weeks

yup, about 3 weeks or so. Also Flushing LOL!!
