"Almost ready" to harvest light green plant

Im confused by this “ weigh a wet pot “ kind of thinking ... it really doesn’t give any useful info. Moisture will evaporate regardless of what the plant uses in a set amount of time.
Also wouldn’t the plant growing skew the weighing of the pot? I would ditch the weighing and learn WHEN to water by pot weight or soil dampness. Like @Budzbuddha said

Also your plant is weeks away and shouldn’t be being flushed this early

they aren't ready yet, too many pistols are still white..
Got a magnifyer? 40x + is good.
I wouldn’t even be looking at trichomes with all those white hairs. OP wait until your hairs turn brown and curl in before you even start checking. It sounds like your looking for cloudy. Instead look and see how many clear are left. Or how many ambers are on the bud. Don’t check leaves check buds

I'm not looking for anything.
I had to flush, that's it. I just took a macro photo and saw that the cloudy trichomes were way more than the clear ones, so I took it like "I had to flush it because it was in a nutrient lockout (my TDS meter wasn't able to measure the ppm of run off water because it was over the max of 2000 ppm) at least she is close to the moment in which a flush is recommended".

At least now I have a better PH (wasn't able to bring it as low as I wanted) and my run off is around 650 ppm.

It is just trying to see the bright side.

Its actually a tried & trusted method used by an awful lot of people: it may not suit your approach but it works, and works well.
I would however say that when its micro managed (I.e actually weighing pots) it is kind of defeating its own purpose
A plant that needs water in a x sized pot will be significantly lighter than same pot that can still go a day or so without feeding.

It is super hard to lower soil PH...I could see the ppm coming down flush after flush, but even flushing only with water between 5,8 an 6,5 I mange to get more or less 6,8 PH only after hours of work...

Guys do you think that, I don't know how many days from now, I can feed some nutes to this poor lady or now that I flushed the soil i can only give her PH water?

Feed a small amount if you feel she is due it.
Then give her time, a couple days to digest.

Btw when you flush for lowering pH it doesn't hurt to go in super low for first half (4 ish). Raising to a low but suitable 5.7:
On balance it will facilitate the medium change quicker, while from first feed it will raise (6.3).
(Its a learning curve)

BTW OP learning to read the plant and the weight of the pot without weighing it is part of the art. You get better with practice. I still use a soil probe to double check any plant that seems close to dry. It’s getting harder to pick up these 5 gallon air pots with mature plants. So get used to using your finger or reading the plant, don’t just rely on weighing. It’s ok to use now but learn other ways as well.

that’s all I was trying to say earlier. Someday you’ll have more plants and won’t want to weigh all of them for every watering.

It sound easy, but I flushed her with water PH as low as 5,7 and the run out was still over PH 7,0. For example at one point the run out was 6,8 "almost there I thought" but I was aiming for 6,5. No idea how but the next flushes(always with 5,8 PH water) I got 7.10, 7.04, 7.14, 7,08 :wall:

I didn't know I could go as low as 4,0 or around there...it will have saved me some work.
Do you thing I should give some other flushes with as you said 4ish PH water and reach, as I was trying, the 6,5(maybe lower) target?
At this point taking another step may be better that haven't done enough...idk, what do you suggest?

Ok Jimmy thank you for your patience, you are such a good lad...

Now that I've corrected my run out at around 650 ppm(my tap water is around 225) adding just a bit of bio grow and bio bloom to the last flush, should I keep it around this level or should i slowly push it up agian around 950-1150 as some guides suggest for flowering?
Of course I'm not doing anything for at least 3-4 days because the soil will take a long time to dry up.
The nutes I've added to the last flush(I did it because the ppm value was going down too much) was just about a half of what I was doing days ago, but as I said, yesterday TDS reading of the run out before flushing was over 2000ppm.

How many weeks in flower now?
Am guessing later half.
OK, so I'd go in at 2ml grow and 3ml bloom for the first feed (few days) plus whatever else you might use (I use bat guano, worm humus, Epsom salts, potassium sulphate and molasses in bloom on top of Biobiz. I use bioheaven too: it acts as a surfactant as well as a stress reliever: expensive but worth it.

However grow n bloom are enough..

That's a lot of stuff!
2ml bio grow and 3ml bio bloom was almost exactly what I was doing. The only difference is that I was doing 4ml of bio bloom.
Don't think I can find bat guano where I live but I can find humus, epson, molasses. Don't know how to dose them though.

If you say that Bio grow, bloom and Heaven will do good enough(at least I have Bio bizz schedule to follow) I'll buy some bio heaven...
Can you suggest a ppm level or I can follow what guides say and go up to 950-1150ppm? I don't know if I have enough time to go up to 1150pmm and then come down to 400 ppm as guide suggest as pre harvest flush.

The plant is at the 23rd day of flowering under 18/6 light schedule.
