I went and dug out some other bloom nutes to see what they look like compared to jacks. These other bloom nutes are stronger in PK than jacks.

Jacks 5-12-26, calcium nitrate, and magnesium sulfate or Masterblend 5 -11-26. If you think you need more P/K then just get some monopotassium phosphate.

That’s a hell of a lot of work to make a gallon of water IMO.

I stand by jacks classic and I love the stuff. Start slow and work your way up with it and then back down you’ll be rewarded with fat very tasty buds.

edit I’ve tried 7? Different flower nutrients and jacks was the easiest and best results. Next would be megacrop. I’ve used fox farms, botanicare line, Mother Earth, and a few others. Always was worried when I’d run out of jacks.

Back in the late 80's, when I first started growing I used the Peters (same brand) 10-30-20 for flower and their 20-20-20 for veg. It worked and I got good flower off the plants. I did that for a year or so before I had learned about pH and the GH Flora nutrients and hydroponics. After that I never looked back.
As we all know you have a huge room.
So buying General Hydroponics must cost you a lot of money.
Did you never try any dry salts anymore? (which would save you a lot of money)
What made you decide to never look back?

Ive said it before and I'll say it again, I tried dry salts, wasted a run on Jacks. I just get superior results and flavor with GH. It works for me, and in the grand scheme of things a few bucks for nutes isn't putting a dent in the profit but a quality or yield hit from changing it up would hurt bad. So for me it's all about you gotta spend money to make money. Nutes cost me around a grand per run including my veg and electricity costs me around 5 - 6k per run, but when I am able to pull 45 - 55 # of high quality flower I just don't care about the costs much anymore. That said though, wholesale prices did go back up to 2k a unit so thats a blessing.
As we all know you have a huge room.
FWIW I only had a couple 400's in a closet back when I started growing.

You use the GH Flora line, the 3 part with FloraGro, FloraMicro and FloraBloom.
As I understand correctly you use all 3 parts because the Lucas Formula did not work out well for you because your plants are really tall.
If that is correct, would you use the Lucas Formula if you would have normal size plants and let's say 16 on a 4 x 4 surface?

TBH I used to run Lucas back when I ran flood and drain for production. Used RO water and the strain I ran exclusively for nearly a decade (land race Shiva) just loved it. Since I moved to Colorado I haven't had any luck with Lucas. Even in flood and drain SoG with RO water. I end up with really red/purple stems, weak plants and low yields. So I can only guess that the strain I was running back in Missouri just liked it but it was an exception. I have tried Lucas in Colorado with many different strains and different grow styles and it just doesn't work for me anymore. So I would have to say no to your question.

That's interesting.
What you say once again confirms my suspicions that I have had for a long time. Just because something works for one person doesn't mean it works for another person.
Different strain, different water, different climate.

For me nutes are real abracadabra.
I want to try out several brands and ways to use the nutes.
Some people I know use the brand Yara. Well known in commercial growing.
They mainly use Yara Brown, combined with Yara Calcinit.
With great results.
But again: Another guy tried Yara Brown out in a side by side with FloraNova.
And although he found the Yara much easier and it gave him a more stable pH, his yield was significantly bigger with FloraNova. And it tasted better, but he also said he was maybe biased on that.
Now he is trying again with a mix of Yara Brown and Yellow and his results are good now.
