I'm trying brother I'm trying. Still keep stumbling on flush on cannabis only related websites.
I think this flush thing comes out of the Hydroponic growing technique that was popular in the 80s in Canada. Somehow the flushing process morphed into soil grown cannabis for some weird reason in the states. These 2 growing processes are distinctly different in approach and chemistry.
Backed up with "I watered my plants now they are growing even better".
I water my plants with an automated process. They drink A LOT more water in flower. I would say likely 2-3 times more in flower than in VEG. So I would argue that flushing is actually giving the plants more water right at the time they need it the most.
Going down the stretch I've seen my flowering plants drink upwards of more than a gallon per plant per DAY. This is how I know they are close to harvest, when they stop drinking a lot of water. So my argument on the "its working" is basically down to the farmer giving the plants enough water right at a crucial time - the last few weeks of flower.
Your plants look fine. Its hard to compare 1 grow to another with your memory of events that happened months ago. Everything would have to be the same in the grow. Very difficult to get there but its doable for sure.
My main goal is repeatable result. There's a whole shit load of science on that topic too.
So @Known going forward since your plants are fine just enjoy what you're doing and keep doing it until the plants tell you different.
On the watering thing I see what looks like CLAY pots you're growing in??
They are GREAT at letting moisture evaporate out of the soil thru the clay. At your next up-pot go to cloth bags which are popular or hard plastic pots. If you want to stay in the clay you will need to water more frequently.
IF they are plastic clay LOOK pots disregard what I've said here on that regard. My very first grow I tried clay. I gave them away as soon as I could. I got terrible results from under watering.
Sweet. I will stop giving plain ro water as it seems to fucking up the ph. I will let you guys know how its going in a week. Peace
@Emilya loves this subject too.#noflushclub
Read @InTheShed write up on this and draw yer own conclusions.
I don’t flush because I don’t use synthetic nutes (no salt build up), so I’ll do the next best thing and tag an expert on the subject.
He loves discussing it. Lol!
Sorry to drag you in Shed.
Oof! Thanks Adam. Bo has this pretty locked down. Flushing excess ions and salts from the soil when using synthetic nutrients is a thing in containers (not on farms), and is beneficial to the plants. Flushing by feeding water only to clear nutrients from the flowers before harvest is not a thing.#noflushclub

This is one sided and completely in error since all it talks about is flushing nutrients out of the soil and does not even address the primary reason we flush our soil... to rid the medium of salt.So pics of 1 plant is all you got? Seriously?
All good brother if you wanna understand how water flowing thru soil read up on CEC also know as Cation Exchange Capacity.
The ONLY thing you can flush out of soil with water is excess Nitrogen. Cannabis plants need very little N in flower because they stored the N in the large fan leaves early on in VEG.
That said, IF the soil is sandy and has very little SOM (soil organic matter) you might be able to flush out some excess N. If the soil has any amount of SOM in it, nothing will flush out. The fertilizer is bound to soil particles in a chemical process (CEC) and cannot be changed with water or leached out or flushed whatever you want to call it.
Its science.
Here's a good read, skip down to page 7 on CEC but the whole article is very informative and what they are teaching in soil science class at university these days:
https://casfs.ucsc.edu/about/public...-Farming/PDF-downloads/2.2-soil-chemistry.pdf
This again is totally in error. All nutrient manufacturers of synthetic nutes recommend periodic flushes of the soil, just the same as they recommend flushing the hydroponic reservoir... and for the same reason: To get rid of the built up salts. I am incensed that you think it wise to spout this misinformation that there is never a need to flush to new growers as if it were fact.I think this flush thing comes out of the Hydroponic growing technique that was popular in the 80s in Canada. Somehow the flushing process morphed into soil grown cannabis for some weird reason in the states.
This is one sided and completely in error
one needs to be able to accurately read and understand the science to realize what parameters were considered and which were not. Just because a scientist made a study, ignoring salt buildup, doesn't mean that anyone else should. That scientist was not addressing the question we have before us today... he was talking about CEC... and as I explained to you earlier Bob, as you keep bringing up this crappy science, to check CEC the very first step that scientist had to do is remove all the built up salt from that soil... salt affects the CEC reading. So essentially, that scientist first flushed, and then ran his measurements and wrote that report. He totally ignored flushing, as it was not part of his experiment. Maybe it would help if you actually understood what you were reading.Those dang pesky scientists always getting in the way. Wish they wood let us imagine things to be true instead of actual scientific proof.
I get it.
