Recommended Flower time?

Growing NL from Oregon Seeds. They say flower time is 54 days......are these estimates normally close to what i should strive for and start looking at the trichomes close to those days?

And if so, when do i start flushing, in general? I water about every 2 or 3 days......So if im supposed to flush for a week, how do you guys determine when the "right" time is after you look at the trichomes? you just taking a guesstimate that you will be fully flushed and the trichomes will be where they need to be in order to harvest??

Q. When you use the word "flush" do you mean leach or watering with water or flush it down the toilet?

I occasionally leach when I get a build up. I often water with plain water throughout the grow. I haven't had to flush any down the toilet (touch wood).

Breeder times are an estimate. I think a 1000W, Hydro, sealed room setup. In reality most go 2 to 3 weeks later.
You wont know how long it will take until you have grown it.

I don't bother looking at trichrome until the buds look ready. 90% brown receding hairs. Some strains don't amber.

I did a NL a grow before last and I think that went about 80 days. (oo seeds).
Just checked- yep 80 days.

Yea, I would check trichomes around that given finish time.

Flushing or more properly called leaching.. or "letting the plant fully metabolize mineral salts before harvest" should be done.

Leaching is best done with reverse osmosis or distilled water. Starting 7-10 days before harvest.

Some find leaching unnecessary but I don't care for smoking unmetabolized fert

Some say leaching isn't needed if using "organic" nutes. Any opinion on that?
My opinion on this based on understanding of soil, nutes, and plant metabolism is this:

Orgo nutes will stay in soil longer so you could flush sooner (urea for example stays in soil like forever so it's not even used in containers)

Orgo nutes during flower metabolize quicker so you could flush later (organic form of phosphate moves so quick it can easily burn plants)

I recently grow hydro semiorganic (some Orgo nutes, some mineral salt "synthetic"-naughty word [just inorganic])

Got any pics so far?

Who says you're supposed to flush for a week.

I know this is not the thread for it, but since we have a new guy asking questions: there is no science for flushing plants.
Opinions are all over the place ... but the science is not there.
You can flush soil ... sometimes it's necessary like if there is a lockout or toxicity. Mostly in veg.
But you cannot flush a plant. Plants don't mysteriously aspirate all their nutrients or return them to the soil (until they're dead).
The concentration of NPK and micro nutes in mature plant tissue is many times more than what the roots pick up.
When you chop that plant, it is still loaded with nutes. And they stay there. They never "leach" out.
If anything,. just reduce the watering schedule near harvest, like you would for any fruiting or flowering plant.

Ya, we are in danger of a thread hi-jack here - hope the OP doesn't mind.

I assumed that some fresh, plain water would get soaked up by the plants and (at least) reduce the concentration of salts (etc.) in the plant material. I guess this is the same theory that many people believe. It seems intuitive, but like most things - it is more complicated than that.

I add a week or two for stretch time and then I factor in if it's been cold and if anything else has slowed them down before I start checking trics, re: flush time forget about it not going there! :roll:
-good luck

Nope I’m in school now for a degree in botany it doesn’t happen.

You're about to not learn what I already know

I'm going for agriculture and food certificate at a community college and I wonder what kind of corporate political big pharma bull they'll be teaching

I already have a bachelor's.

As do i this will be my third, already have a masters in computer science, bachelors in business.
I own my own farm too. I’m not planing on them teaching me anything I don’t already know just going for the paper is all.

In good soil, just go easy on the nutes and there will be no issue that causes a need for a flush.
I recommend 900-1000 ppm/6.0-6.3 ph in soil, every 3rd watering, and you shouldn't have any problems.
