The metric scale was invented by the French I think, to try and make it easier to understand (believe it or not), and also to fit in-line with scientific measurement, and maybe something about revolt too. All it really is, is just a system where were multiple or divide by a 1000. Though it does...

Sorry for late reply, been building a grow room, what a distraction that is for my existing crop. Anyways, I added K2SO4 to my res now as she is nearly done (thanx for the reminder). Yeah micros is a whole other issue, why I had separete formula for dealing with them. The plant will get what...

I have slight feeling that the Hoagland solution has too much K for Cannabis. Antagonizes Ca and Mg uptake. Tomatoes apparently just need more K tho. Intresting that you running starter solution and then use a different refill solution. I read a paper by Voogt (1992), on reusing nutrient...

Intresting sounds like the Silicate acts as a alkaline buffer or is eating up your acid buffer. Most people don't know what a buffer really is. It's not just a pH downer. Sulfuric Acid drops the pH, but Phosphoric acid is a buffer system per se, so it drops the pH not too far, but it keeps it...

Are you not having problems with the silica in your stock solution? I hear various things about this

i actually havnt found one, and Im using sulfate salts for my micros except iron, which i use EDTA. I took high school chemistry and when I was 14 I read my mom's chemistry college books because I wanted to make gunpowder and rockets lol, so i learnt the language young. It's tricky i...

Because it strated out as milli-Moles because we work with a salt say MgSO4 to get our targets... we balance the chemical formula using moles, and then convert moles into mg and into ppm. Like the molar mass for 1 milli-Mole Mg is 24mg. And the per litre bit assumed, ie 1mg per litre of water...

Here's how I compute the fert salts i need for my stock solutions. Note I just use dosage rate instead of bothering with tank size and other nuisance factors. Also note I use 1 mathematical model instead of several separate and smaller steps, where I just plug in the various numbers for the...

Yeah thanx maybe one day :) Here's how I balance. 1mM means 1 milli molar unit ie 1 milli molar mass. Bit like a rubix cube puzzle, and I trust my own creative problem solving abilities over a "best fit algorithm". Let's think in terms of molarity first ie 1 milli molar mass unit per litre of...

Yeah heard that too. Would love to see the science behind those nutrients causing smells. I actually use my own equations for my nutrients mixes, should get them checked out by others. Good read thanx

No pics, maybe when lights come on i can take, but relly is typical upper leaf rust caused by calcium lockout I rate. I can use more extraction, app transpiration helps draw Calcium into the leaves. Plants are bit cramped, unfamiliar sativa strain. Was running 100:50:150 NPK on my last batch...

I started with a high P Hoagland solution at about 50% ec, then went down to N-P-K-Ca-Mg-S = 100:50:150:100:95:44:69 was fine for one strain in winter, but now another strain in summer here leaves burnt and 'praying leaf' turgur dropped Micros for both stock solutions were: Fe EDTA = 3ppm, Mn...

I'm running DWC, and I found those numbers are very hot. A few days ago I switched my bloom res down to N-P-K-Ca-Mg-S = 50-42-81-50-28-38. Still keeping P high but basically took a small fraction of the other numbers just to get my ec down.

I'm formulating my own stock nutrients. Was wondering is using Calcium Nitrate and no other ammonium salt is fine --- instead of using Calcium Ammonium Nitrate. It's very warm where I live, and I need to cut down my nitrogen levels. Anyone tried this?

I never really worried before, because I figure that the better the MJ is grown, then the better the MJ quality. Like a fine single malt Irish whiskey, a great grower can still be a distinct artisan, and still be sought after and showered with cash. Yeah step one of any venture is the ID your...

Perhaps I should make money then by selling all these people hydroponic systems, organics, fertlisers, lighting, automation, genetix etc

I see people saying that they cannot move their product because the market is saturated with prime nugs. A green rush is happening and all growers are moving there app to think they can get rich

Hey guys. Cons Canada: Yes everyone is saying Canada is going to legalise, but others are saying it's going to be a government controlled market, where you sell to them. Anyone else = worse penalties than before legalisation. Also I see SOP licensing seems like a bitch and a half. Cons USA...

Funny...I actually live in Africa lol

I've been using liquid GHE fertliser for years, always had Calcium issues. SO I started mixing my own from salts. Fun. Though I can use some expertise How much calcium is generally adequate for DWC? My plants aren't complaining, yet, 4 weeks into flower, but being optimal can't hurt. Worried...
