When to start flushing, harvest, first grow so looking for some help.
First grow, in hydro, DWC. Using CFL lights for this grow, I have about 16-18 26Watt CFL's, a mixture of 2700k and 6500k. I started flowering on 4-11-12... So that makes today day 45 of flowering... I'm growing sensi seeds Big Bud, which according to their site has a flowering time of 50-65 days... I do not have any flushing solution, so I was just going to give her plain distilled water to flush before harvest. My question is, when? I've read to flush 4 days before, 7 days before, 10 days, and 14 days! I know I want to wait for about a 75% cloudy 25% amber to harvest, but if I want to harvest it THEN, how do I know when to start flushing BEFORE it gets to that point. Here are a bunch of pics, I have my wife going out later to get me a microscope from radio shack so I can look up close at the trichs, but I'm imagining they are all still clear... I don't know though since this is my first plant... Any help would be awesome right now, and yes, I know, this thread is all over RIU, but the information varies from thread to thread and it makes me feel better to post pics and get first hand opinions on MY plant and what to do...
I'm using greenleaf nutrients, they imitate major brands, so I got their general hydroponics flora series imitation... gro,micro,bloom... I'm running at about 1000PPM right now... 2.5ml Gro - 7ml Micro - 16ml Bloom per gallon of water.
Here are pics.
some people flush
some people dont
some people do it for days
some for 2 weeks
everyone has a different way of doing it
theres no right way or wrong way
just do it the way you think is best...........
i agree with missphoebe, i dont flush my plants and nutes to the end.
post some pics up in a week or so so we can see how pretty they get!
good looking plant btw
I'm just afraid of the harsh smoke and crackling. But then I read that flushing at the end will starve the plant when it needs food the most. Considering my plant right now is drinking a gallon of water every 48 hours I'm thinking a 4-6 day flush would be good. Another question though. If I start to flush when the tricks are 25% amber and the rest cloudy, by the time in done flushing what will the tricks be... How quickly do they change to amber once you see the first ones.

I always flush in the first day of the "harvest window" per the breeder then finish with water until they are done, however long that will be (3 days, two Weeks, whatever).
I'm using synthetic Nutes the whole way until week 6 of flower. Then at week 6, I plan to flush with water, then I'll let them finish with organic nutes until harvest. I'll let you know how it works!

Hello if you use compost tea do you have to flush before harvest or just slowly dilute it till its water ????
the idea of flushing is so that the plant uses up its nutes that are already stored in the system. Meaning, even though you are flushing the plant is still running off of stored nutrients... so the idea that yo are starving the plant is a bit wrong. I can only speak from personal experience... and I've tried a few different ways... but I flush with 10 ml florakleen/gallon 5-10 times over 5 days.
without florakleen i would guess more gallons over more days.

Don't worry it's not really Manbearpig. It's me... Al Gore.
Makes sense... the thing about it using existing nutrients to deplete itself... I'm getting this idea this is one of those things where I'm just going to have to try something and hope it works... So this is my idea... when I see a 75% cloud and 25% amber trich mixtures I flush with distilled water... Do that for about 4-6 days and by 6 days what mixture will I be looking at 50 cloudy 50 amber? My only concern, again, because this is my first plant, is... How quickly to the trichs turn colors?

If your wanting a 75/25 ratio, then when 90% of your triches turn cloudy just start adding plain water .. Imo people get more of the harshness they experience not from the flush but from drying and curing to fast..
