PH , Ricky,
I wonder if the HG method concentrates the nutrients within the bag. If I fed my plants ec.1.2 they would be pale and spindly. I also wonder if that's why they call for a plain water rinse every so often.

So what I am getting at is even though PH is feeding with the most dilute mix of the three of us, could it be concentrating in the root zone as the plants uptake water in the heat? That would explain the heavily fertilized look, but in my system.that condition would also result in wilting, which PH does not have.
Puzzling.

PH is that nutrient measure by weight or volume?

Ricky Shaw · June 20, 2016

PH is mixing at the same ratio I am. He is mixing in 250gal batches, me in 55gal. He is adding pH adjustment, I'm not.

I have dropped temporarily to an EC of 1600 because of increased evaporation from 90 degree days and will resume regular feedings shortly.

Ricky, your rates above are what I had been using for the last few weeks for plants that had the third truss blooming.
I felt like it was too much. You had no issues? Maybe your plants are farther ahead?

Nematode · June 20, 2016

For reference I am north and plants are single stem and a bit smaller than yours. They are getting approx 20oz/day/plant. I havent checked runoff ec or volume, but the bags are heavy and plants not wilting so I know there is some runoff occurring.

PureHarvest · June 20, 2016

I am adding by weighing out the dry ingredients in ounces.
The rates listed on the label for my stage of growth would have been 20 ounces of CGro, 20 ounces of Calnitrate and 10 ounces of mgso4 per 100 gallons of water.
I had been bumping that to 25, 25, and 12.5 because my ppm was not hitting the 1,500 ppm they were saying it should. That is where the tuncheon vs hanna thought came into play for me.
Yesterday I did 20, 20, 10 per 100 gallons.

Ricky Shaw · June 20, 2016

I did seedlings at EC 1600, and at the plants 4th internode stepped up to EC 2000. I do not plan to go to their recommendation of EC 2200 uS/cm for hybrids.

This I think would be too strong.
Earlier you put the same nutes in 250gal, which would be ok.

Ricky Shaw · June 20, 2016

I like when we check each other's work. I took internode to mean flower cluster, I stepped it up too early, they look fine though.

My mistake, that was per my 250 gallon tank!

Gerardo · June 20, 2016

I was surfing to find a local supplier of water soluble dry nutes, and bumped into this.

Just in case you guys need to re-up, free shipping, with no "hidden" increase in base price.

Any word on Peters Professional Combi-Sol?

Which Grow More is the best fit for our endeavor?

PureHarvest · June 20, 2016

That is expensive, unless of course that lasts you a year or more.

50 lb bag locally is about 25-30 bucks.

What is Grow More?

U are correct sir. I'm gonna find the local source for Ca Nitrate.

So I just made up another tank.
250 gallons of water
20 dry ounces of Chemgro
20 dry ounces of calcium nitrate
10 dry ounces mag sulfate
43 grams potassium hydroxide for pH up

On my Hanna meter after thorough mixing with submersible pump:

PH: 6.2
EC: 1.61
PPM: 1176

This is the second stage rate per hydro gardens' instructions (plants between 2nd and 4th flower truss).
Supposed to be 2.0 EC and 1500 ppm.

You can see my numbers above.

The conversion chart says my Hanna ppm at 1176 is about 1610 ppm
But the EC would be 2.3
So the ppm is close, but the EC is what gets me

Ricky Shaw · June 20, 2016

If your meter is set to Trucheon scale that looks to be correct, an EC of 1.6 would be Truncheon 1120, but a Hanna ppm of 800ppm. I try to only refer to EC values.

And I've thought that Chemgro formula is light. Your readings seem to agree with that.
