Flushing before harvest

Im into week 6-7 for my outdoor strawberry cheesecake and Bubba Kush. I usually mess up this part and never leave enough time to flush. Will now be the idea at time to start or should I wait a little bit longer?

Yea you can buy growing outside is not as a need like indoors. Roots grow into ground just a week would be good.

Are these plants in-ground?

No 10gal pots ocean forest

What are you trying to "flush"?

Those flowers aren't nearly ready, you should still be feeding

Keep feeding. Weeks to go yet.

I struggle with my timing. I see all the amber on my sugar leaves and freak out and forget everything I’ve learned and start second guessing.(first pic) thanks

Trichomes on sugar leaves are not a good indicator of harvest time. A combo of pistils dying back, calyx swelling and bud trichs will tell you when it’s time. Flushing works well for toilets and can actually be detrimental for plants if done too early.

Haha

Flushing, is a myth, and not supported by facts.

I don't subscribe to flushing but if a plant pulls in nutrients/ minerals then gets chopped the water in the vascular system evaporates leaving the minerals behind, we know evaporation leaving salts behind is accepted science.

Giving them water for 4 days *only* after they're ready to chop eliminates it as the sap measures 0.0ec.

Not according to the above study. Unless one has overfertilized the soil, to the point of plant damage. A plant, will only use enough fertilizer/food to be healthy.
Above study says flushing does nothing to remove fertilizer from the plant.

And are newbs going to pull off a perfect timed grow???funny shit...flawed argument....
Most mewbs overfertilize,i call a newb someone who has less than 10 indoor grows under his/her belt.

Very well said,someone who understands the science,refreshing these days.

So, how does one “flush salts” out of an organic grow in hot soil? Or does flushing not apply here?

I have yet to see any science definitively support the practice of flushing. There’s some theories of low probability of positive effects based on limited samples but nothing concrete/extensive. There’s a loose argument on the possibility of reduced chlorophyll/elevated anthocyanins from flushing which may help improve bag appeal/appearance and possibly flavour? Again, limited sample size and low probability.

To date, there appears to be more science showing that flushing has little to no positive effect and a higher potential for negative effects. I have yet to see any empirical data supporting positive results from flushing with some suggesting just the opposite. There simply has not been enough studies done/published data except for “loose” evidence of potential positive effects if plants have been given high levels of fertilizers during the grow. We are talking like a 10-40% chance a plant MIGHT benefit from flushing at between 1-2 weeks pre-harvest and only if fed at high rates.

I digress, the takeaways as I see it:

1. Do not flush any earlier than 1-2 weeks pre-harvest.
2. No benefit unless plants have been blasted with nutes.
3. Even if plants were blasted, there is not enough data to prove that all cultivars will benefit or what that benefit translates to as far as quality/yield/etc.

My advice would be to do what makes you feel good as long as it is no earlier than two weeks before harvest…as I doubt anyone on the planet would know the difference smoking bud from a plant that was flushed and one that wasn’t.

You can, trichomes looks like ready or near-ready

For the record i grow organic and do not flush.when you say salt build up people naturally believe its sunthetic nutes cause over time they build up and can be toxic as well as cause major nute lockout issues,there is no salt build up in organic cause you feed the soil and it feeds the plants.
So like i said,when you bring up salts you must be talking about synthetic nutes that i would flush....100%
But you never once said organic.
