Still doin this or switched things up ? Hydro ?
Phosphorus or Potassium during flower???

Yes. I'm still using the same stuff I've been using for years. Hydro flood and drain, DWC, coco, and soil. Of course with soil I don't feed every watering. I'm currently mixing up a batch of nutrients to feed my vegetable starts using the same stuff I use to feed cannabis. Plants use the same nutrients. You can mix them in different proportions but in the end the same nutrients can be used for almost all plants. I just choose to buy stuff as dry chemical salts and mix them with water myself rather than paying the exorbitant costs charged by all the fancy label and cool sounding name companies.

Yeah that's what am atfwr doing myself but get bit confused with it all people saying different npk ratios different ppm elements eg..N 100ppm..P65ppm..K170ppm ..ca.100..Mg..75
What are you ruing mind on you now ? Npk & element ppms ?
Have you used lie the 3-1-5 flower or all way though ? 1-3-2 ratios 1-1-3

Did you mean potassium silicate? If not, how much potassium sulfate do you add through different stages? Thanks in advance!

The below is elemental ppm (not the same as the ppm on a meter). I guess that is where a lot of confusion comes in for people, as it did for me. They are two completely different values and highlights the absolute bs contradictory or outright wrong info around growing mj.
COCO (Half manually fed, half blumats)
Elemental ppm in veg:
N - 150
P - 38
K - 160
C - 95
M - 60
S - 65
Elemental ppm during stretch, to the end of week 3:
N - 150
P - 60 (bumped up with mpk)
K - 189 (mpk)
C - 95
M - 60
S - 65
Elemental ppm from week 4 to end of week 6:
N - 95 (half the amount of N from Cnitrate since stretch is done)
P - 84 (further increase of mpk as the established bud sites begin to fill out)
K - 216 (mpk)
C - 40 (reduced with cal nitrate, although tap water holds some C too, so ppm will be slightly higher than shown here).
M - 60
S - 65
Elemental ppm from week 7 to end of week 8:
N - 95
P - 60 (dropped to it's previous level)
K - 189 (dropped to it's previous level)
C - 40
M - 60
S - 65
For final week 9 the above ppm of all is cut in half
N - 50
P - 30
K - 95
C - 20
M - 30
S - 32
No flushing is done, since the above final week ppm and previous ppm levels are on the low side, any slight nutrient build ups from previous weeks will sustain (in theory) for the final week. 20% run off is maintained during the last week. Prior to that, with such low over all ppm at any given point, they can go with no run off for more than a few feeding's.
Not saying all of the above ratios is 100% correct, but just an idea of ball park elemental ppm changes from veg and across the 4 flowering phases.
On another note, anybody with more experience who can recommend ratio changes please do so. I always got the feeling K was too high during early/mid with the above, although it's still within the boundaries from everything I've read. It would require a base change to adjust, so been putting that off.

Per the science books Phosphorus is responsible for resin and flower production and potassium is more roots related.
So should P
So should P be boosted near the end of flower?

Im a new grower myself and I've gone pretty much all natural so far... using things I've learned throughout the web and combining them based on My own knowledge...
I started with a good NPK based mix with premixed perlite, then added to the top of it some used coffee grounds for more nitrogen Later (it takes awhile to break down naturally so I started it early so the release was consistent and equal) i also put a banana peel or 2 on the bottom of the soil layer for a potassium boost later on as well. Once flowering started I added some burnt wood ashes to the top level for (P) ND just kept watering and let nature do the rest... i just read my plant and went from there afterwards adding little bits of those things later. Idk how it will end but so far my results have been very nice for basically just watering them and no powdered or chemical enhancements. ..im hoping it preserves a good natural flavor.
I'm in like my 5th or 6th week of flower now and my buds are huge already and still pushing out little white hairs daily. Im. Going
For quality over quantity too though as my crop is just for me and the wifey... and the grows are my sort of therapy lol. I find d growing very relaxing and calming... super therapeutic!! Anyways
I know people will probably Reem me for my tactics, but for a first time grow in my backyard with no special tools( I got a bucket, the sun, and a garden hose lol) I find it very easy and cheap. Plus if my logic is right, there is a nice reserve of nutes if I ever lose track of them. (And it's basically from leftover stuff I had bought for the family anyways!)
Not to shabby for my first trial and error grow lol

Exactly what I was gonna say apart from the Ca bit which I’ve just noticed switching to LED.
Extra P when buds forming then higher K for flavour, density.

For chemicals I use a 4-20-39
15.5-0-0 Calcium Nitrate
Epsom Salts
Going by tissue analysis weed likes a 1-1-2 ratio all through its life.
In weeks 2.5-6 in an 8 weeks flowering strain, you can increae the P-K with Monopotassium Phosphate. 0-52-34
When first starting in seedling use a small amount, 10%, and feed every watering. Each week gradually up the fertilizer PPM. I usually go to about 25%-40% of recommended max dosage, and feed each watering.
The last 2 weeks ut the feed in half. Dont flush. Flushing is a myth.

No, actually I'm the master, lol.
I'm a firm believer in boosters. I have a root booster which is 1/4 tsp silica, 1/8 Kelp and 1/4 of Humic acid...I use early bloom, mid, during and late bloom boosters as well...early booster is 1/8 phosphorus 1/16 potassium, 1/4 OmniA...My booster NPK values are extremely high 20-61-50 so unless you are using the exact nutrients as someone else you'll need to figure out whats best for you...
PS> Different plants will respond differently to different boosters but unless you have your plants dialed in, meaning max EC/PPM, you won't know if a booster works or not. I have some plants that eat 2600 Plus PPM and some that show stress at 1500ppm. I increase my PPM my roughly 200 until I see mild stress then back off and I know I am dialed in on that plant. Meaning its eating the max so a booster really helps, but if you have a plant that needs 2600 and you're feeding it 1200 you will not see much difference if any with a booster
Strain?

Exactly what I was thinking. Not you must have had 19 years of larfy bud
