Flushing!!!!

So the question here is when should i flush??? Well my High Times article says to flush 2 weeks before they are ready and i dont have a microscope to check the trich's. My plants take 45-50 days flowering and they are on their 33rd day!! So that means that i should flush this weekend ...correct?? Thaks

It depends a week and a half or two weeks is fine. I flush like 6 or 7 days before harvest but I use clearex to leech the soil. 45-50 days flowering seems pretty short Id def go atleast a week longer than that
