TA Nova Max bloom has Humic Acid in it already as a additional chelator.
Peat/Perlite has a better CEC than coco, in theory it should hold more and also exchange more cal/mag also other macro-micro nutrients. But i start to think that the LEDs grows needing more cal/mag supplementation is true, principally with almost soft tap water.
Took a read here with my gf Kindle, pretty easy reading book.here’s the man with all your answers..View attachment 1992143
Yep coco relies more on calcium and magnesium to buffer the media and be stable.In common:
LEDs
Soft water
Kissing-cousin mediums
As I changed out my res yesterday, I somewhat waffled over my CalMg strength as GH Flora has some. My research showed that coco needs it badly so that's why I went for a full mix.
But wait there's more!
I came from HPS, albeit decades ago, and began recently with LEDs. I had no clue they were that much of an influence. By looks, mine have super small indications they want more.
Super timely post, and thank you so much for explaining it so nicely.

Yep nice, sent him a msg, waiting for an answer.if you purchased the book either way, i’m pretty sure you can connect with him for further updates, which i think there’s already been one..
john is good friends with bubbleman..
Could you tell us more about humic/fulvic acid? Why it's used and how it's bought and used? I never heard about these until here.......thank you...Interesting... I wonder (since you're running 50/50 peat/perlite), how much your medium differs from coco/perlite in terms of needing CalMg?
Also, are you using humic/fulvic acid supplements?

No doubt. And we need to know how to get them, amounts to use, how, when.....From my readings, humic acid helps with nutrient uptake, medium buffering/cation exchange. Some report better root structure?Lots of variables, though, for that.
Fulvic seems a bit more mysterious, but same benefits... Roots and nutrient uptake.
Coco has been a interesting learning curve for sure! Those of us coming back from the 90s have a lot to catch up on.

Also its a natural chelator, helps unbound soil/media of Phosphorous and make it more available to plants, it contains a lot of carbon witch helps feed microherd in media and revitalize soil/media life in general.From my readings, humic acid helps with nutrient uptake, medium buffering/cation exchange.

Apparently it means becoming more knowledgeable about buffering and cation exchange.
Hey, if there's a legitimate issue......To keep from trashing Trash's GroJo, I'll start a thread in the ferts and nutes forum.
Kind of a bumpy road switching to LED's for flowering tho, but i'm gonna get it dialed in, we are persistent.A great setup and some beautiful plants you have there.

Let's see if the theory that plants under LED's need more food is true, the potassium deficiency/lockout stopped already.
Some little tip burn still there but doesn't look like overfeed, this tip burn looks different not something i've deal with before, it's "rusty" looking and a bit larger than a start of overfed tip burn. Maybe was caused by too much light at transition cause new leaves doesn't show it, still investigating the true cause.
