I must say I'm surprised at how much Na that brings along for the ride... I'll contact solufeed and ask them to confirm that for the product I've got. I've spoken with them before and they said there's only a very small amount of Na.. but I've used the Ca 9.5 in quite high amounts successfully...

@Skybound420 can you get a chelated calcium? I use this https://shopfront.solufeed.co.uk/solufeed-ca-95-edta-226-p.asp The manufacturer says it's 3 times more effective than regular calcium, so 33.3 Mg/L is equivalent to 100 Mg/L they say.. It works great as a foliar too. Also keeping...

It's elemental P. Personally I always refer to the elemental mgL/ppms. Peace BL

Yep it's been a while lol. I'll update in a few days with pics from all the weeks. Peace BL

While I'll not tell you that you're wrong I'll present some evidence for why I believe plants do not simply pick what they need from a recirculating hydroponic solution. For this I'll reference a paper from an 18 year study into nutrient management in recirculating hydroponics. For the record...

What does it do when it no longer needs NO3? If uptake continues once the "need" is satisfied, is that still being selective? Peace BL

Get a large barrel or water butt and mix your fresh nutrient solution up in there and let it reach the desired temperature, or heat it to the desired temperature. Makes for quicker res changes too. Peace BL

Plants don't pick out what they need.. Different nutrient elements have different forms and rates of uptake/removal from solution. NO3, NH4, P, K, Mn: active uptake, fast removal. Mg, S, Fe, Zn, Cu, Mo, Cl: Intermediate uptake. Ca, B: Passive uptake, slow removal Bugbee (2003) Scientific...

Zkittles X Skunk 2 full weeks flower. (Recently reduced lighting to 11 hrs to induce flowers) Day of the Triffids I reckon :roll: Peace BL

Yes mg/L is parts per million! Not just saying it because I'm British, but it's much better and easier to work in the metric system where nutrients are concerned. Litres, and grams directly relate to Mg/L which is PPM. No conversion factors or any other things to be misinterpreted. I thought...

Buds like this one will use up over 320mg/L K in my experience. P reduced to around 15mg/L from mid flower. Peace BL Edit to add pic

Hoagland is specific to a certain amount of water per plant. And I don't think they topped up with full strength solution. Maybe 1/3 strength.. I'm not sure. Yours look great there.. Not too sure about that yellow growth near the bottom center of the picture lol.. You can easily go at least...

Not sure what country you're in but I use solufeed TEC for all micros. https://uk.solufeed.com/products/chelates/solufeed-tec I use a bit of 7% Fe EDTA too. Peace BL

Cannabis plants that grow big flowers can use all the K in Hoagland and more I've found, I've run over 300mg/L to good effect, but the plant must be using it IMO. And yes you're right keeping K high in the active parts of the recirculating system can inhibit Ca uptake. But K is removed quickly...

A nice article on water disinfection. https://gpnmag.com/article/grower-101-water-disinfection/ Peace BL
