I can get the same results either way, one less bottle to mix. Less formulas as you use it all through the grow
Can you use all the extras with it...Their "expert" lineup? I like a few of them, like Armor Si...I'm about to use GH for the first time in a aero setup and thinking of trying the Lucas Formula...I used AN in the past and wasn't crazy about it.

Advanced is the most marked up nutes out there. Its insane what they charge.

Yes you. An, just keep an eye on your EC. That’s why I wanted the spreadsheet in this thread to be able to add to it

I know renfro had some awesome spread sheets posted somewhere but I haven't been able to find them again

I posted the link to his thing on the 5th post. Or has he posted some of his feeding charts?

Edit: or do you mean these?

And if you look at his spread sheet you will notice that he is using a weaker Lucas Formula and adding in calimagic and armor-si because it is already on the high end of what plants can take, you have to back off to add in. Friend of mine had guy in the hydro store try to sell him a 14 bottle lineup of something. That is why people like Lucas. Also less chance to f it up when you are high and mixing your nutes.

As to the lucas discussion. I found it to be superb for smaller plants in flood and drain so long as coco isn't involved.

When I switched from large plant count flood and drain SoG to growing giant big ass trees it doesn't work so well and I started having to add the grow. Anyone out there growing giant trees indoors with lucas? I would like to hear how it works for them.

Who is using this feeding schedule in flower? This is what the MJ growers guide recommends for flower? 3 ml micro 0 ml grow 22ml bloom /Per gallon. Seems way out there? I ran mel Frank's veg numbers through renfro's spreadsheet. Idk PPM over 2000 in veg seems kinda crazy. Most people on this site say they don't use more than 5ml per gallon ever! So what's the deal, why such huge differences? What do you guys think? Mel Frank and ed Rosenthal are legends! Shouldn't we show respect and trust there numbers? Who out there has run either of these feeding schedules?

Either something's fucked up on their end or the nutes they're referring to are extremely weak.

you are still missing the point of it. way back when the only published nute schedules were mel frank and pH imbalances. a bunch of growers got together to find out what NPKMg target ppms were actually best for cannabis. they came up with 100/100/200/60. then they calculated they hit this target with 8micro/16bloom and the Lucas formula was born.
