It's the green bottle (the one lucas lacks) that's high in K.
Additives that raise ph

Your saying GH floragro has the KOH your talking about in it? I thought you meant something totally different.
I'm actually doing Lucas with a bottle of floragro and tiger bloom and getting higher K than the original Lucas with 104-104-220. 10ml each of the tiger and gro per gallon.
I wonder if that's a better combo than Lucas because your getting the KOH like you say and Lucas only has 160ish K in it I think. Offcourse you can always add some of the gro with the origional formula.

Well I’m happy using rhizo on the rare occasion that I put a little too much PH down in my mix. I’m getting good results this way so il stick with that and I have money so it doesn’t both me spending an extra £2 when I need to add about 20 ml of rhizo to bring the PH up a little. If your getting good results with potassium hydroxide then that’s great stick with that dude each to their own. Happy growing.

He's not really talking about additives I think he's talking about the GH green bottle (floragro) that's high in K.
So with the rhizo your not using it all the time just when the ph needs to be raised. Wouldn't your ph need to be raised all the time. What are you adding that reduces ph that you only need it once in a while.

Oh right just see the post below mine and thought it was referring to me. My bad. Il keep nose out lol i only need to raise my PH if I’ve added a little to much PH down.

No it's ok dude your fine. It's interesting that the rhizotonic wouldn't be something that's used on a regular bases. You say you only use it occasionally to raise ph if you use too much ph down. The guy in the video says to get it if your looking for a root stimulator. And to use it mostly in transplanting or early flower. So it seems it would go a long way if you purchase a little 250ml bottle and wouldn't hurt.
To clarify all the products mentioned in this thread.
1. Rhizotonic
2. Silica (not recommended)
3. KOH (floragro)
4. SLF-100 (mycorrhizae)
5. Nirvana/Liquid Karma or Zeus juice
6. Bioag Ful-power
7. Olympus up
8. Demeters destiny
9. Bloom chaos
What do you guys think about Zeus juice vs nirvana/karma? Do you think a chemical wash (nirvana/karma) would be better for coco vs an enzyme wash (Zeus).
Or do you think something like ful-power would be better overall do to its concentration.
Nirvana, karma, zues, and ful-power are all the same price at around $20. Which one would you guys choose if you had to pick one.
To keep it simple it seems like Olympus up would work really well with my coco and Lucas. I'm running out of GH ph up and it's something I can use all the time.
The demeters destiny sounds nice when I run out of calmag plus and it's the same price so why not. It would probably offset the Mg in my Dolomite and the coco fiber itself so I don't get a high Mg load like I would if I use calmag plus.
The mycorrhizae would be cool because I do like to reuse my coco. I already have cannazyme for that purpose so a product like SLF-100 would be interesting.
Then for base nutes Lucas can be used with a tad bit of the floragro to get the KOH in there so the K is a little bit higher to about 200. So your only adding a little tsp of the floragro to the Lucas. Just hope I don't get potassium burn with that but I think it should be fine.

Idk about that seems like too much hassle.

I'm liking that Olympus up more and more with the Demeter destiny combo in coco. Especially with my tap ppm being 60ppm. It's like your feeding them an extra nutrient.
I heard the Olympus up is liquid limestone. I already added Dolomite lime to my coco and I think it's a bit much with the calmag plus. My Mg load is too high using calmag plus with Dolomite and the coco fiber itself being 40% mg is redundent.
Thats why the Demeters destiny and and Olympus up combo sounds so good because your getting exactly what the coco needs and using it all the time. I just wouldn't add the Dolomite anymore with the oly up because it being liquid limestone anyway.
Do you use H3ads formula or Lucas with your coco at all? And how much of that demeters destiny do you add?
Right now I'm using Lucas maxed out because my girls are hungry bitches taking anything I throw at them lol. Thanks for all the responses guys.
@11:25 he mentions bonemeal absorbtion and ph. The bonemeal needs to be absorbed at 6.2 ph or over so it wouldn't be good for coco anyway. A bit off topic but then he talks about the Olympus up.

Yea mate I use it as a root stimulator primarily but I also use to raise my PH if needed.

The main ingredient of the green bottle is potassium nitrate, which is a great source of potassium.
Potassium nitrate has an NPK rating of 13-0-44.
In fact, once you know this, there's really no purpose of buying the green bottle (Assuming you did you use). Just replace the green bottle with potassium nitrate. There is no potassium hydroxide in it.
Potassium hydroxide is what's used in pH up. The reason sodium hydroxide isn't used is because it would give the plant too much sodium, and the reason calcium hydroxide isn't used is because it's not as water soluble.
Potassium hydroxide has an NPK rating of 0-0-83.

I am not currently using Lucas formula. One of the most important steps in Lucas formula is the strength. It should be around 2.0 EC. Also, the formula shouldn't be screwed with or it isn't Lucas (6-7 grams of MaxiBloom and done - or 8 micro 16 bloom).
I do currently use 5ml/gal of Demeter's.
As for ph, not sure why you think ph over 6.2 isn't good for coco...
All those charts floating around showing nutrient absorption by ph are largely incorrect.
All of the elements are readily available anywhere in the 5.5 to 6.5 range, even more so if you use fulvic acid, amino acids, beneficial microbes, etc.
My ideal for coco is in the 6.0-6.4 range.

That's strange because everytime I look up coco and ph on the forums everyone is always saying 5.8-6.0 with 6 being the sweet spot or maybe 6.1 at most if you don't over do it. Unless this is outdated information. I thought soil was 6.0-6.5.

I filled up my 5 gallon bucket almost to the top where the line is so I know exactly how much tap water was in there and made calculations on how much ph up I needed to add to compensate for the loss of my nutrient mix. Ended up putting 40 drops of the GH ph up which isn't bad for that much water. Now to to see what ph I get when I add nutes.

One of those old wives tales, like don't swallow chewing gum...
The charts show where the most absorption theoretically happens, and for some reason people translated that to mean ONLY available in those ranges. Plus, there are several charts floating around, each with different info.
People running coco at 5.8 would get more "free" calcium by running 6.2-6.4.
Soil can handle higher ph.

All these old wives tales what's going on lol.
My nute mix without ph up is 3.8 so I ph'd my tap to 7.9 to compensate for a target range of 6.0. Than added my nutes and it only came out to freaking 4.16 wth.
That means I have to ph my water like over 10.0 or something before adding nutes what in the world.
Edit: my calculations are telling me my water has to be 10.0ph for me to get a ph of 6.2 after adding nutes. Going to ph the water more and try this again.

I always add nutrients and additives first to get to the target EC, then wait 15 minutes or so, then check ph and adjust accordingly (then I add any living beneficials). Many nutrients are ph buffered and will try to self correct in a useable range.
I'm fortunate that my tap water is ph 7.

Yea this GH ph up is way too weak. Only raises it like 0.10 every tsp. I heard AN ph up is strong I may get that. I doubt Olympus up is strong I have to email them.

What nutes are you using and how much? If your tap is 7 than your nute mix is stronger than mine.
My tap is 5.7 I had to bring it to 9.75. After adding a 104-104-220 Lucas mix with 10ml each of floragro and tiger bloom w/ 5ml calmag plus I got 6.27.
I'm still surprised the 5.8-6.0 ph in coco is an old wives tale. Everyone was saying it. I'm going to do 6.0-6.5 like you say. I'll probably get better uptake for all nutes that way. You said calcium is the only thing taken in at 5.8?
