trichs how long

hi how long does it take the trichs to turn from clear to cloudy. i have a blueberry 5 weeks in flower. also when i flush do i empty the res. or just keep adding plain water at feeding thanks

Some plants take up to a month, others go in 2 weeks or less. I usually start my flush when about 2 out of 10 trichs are amber colored, then flush until at least half of the trichs are amber colored. From clear to cloudy can take a short period, but you want more than just cloudy trichs.

When you flush you empty the res and fill it with plain PH water.

5 weeks is early for any strain you most likly gonna need 7-8 min best case when guessing. if i were you goto radio shack and get the 10 dollar microscope and look at the trics your self. as for flushing plan a day you want to harvest based on tric maturation ratio and flush about 2 weeks (soil) 1 week (hydro). and if its a soil grow get some mollases in there! time makes all the differance with weed. if u dont wait long enough all of what u have done wont be as good as it could be!

i all ready have a microscope that how i know their clear and thanks for the reply
