Our grow styles and demands sound similar. Only variable is I use Promix HP for soil so not sure how your soil compares. I PH between 5.8 and 6.2, usually around 6 on average. I started out using RO water and had some minor issues. Going full tap water improved any issues 100%. My tap is around 250ppm so your water is not too hard....don't strip those natural nutes out of your water. My ppm's of Jacks throughout growth range from 250ppm to 700ppm. Only supplement needed besides the Jacks is around 100ppm of Cal/Mag once or twice (usually once during veg and once during bloom). I'll also add some potassium sulfate 2 or 3 times throughout bloom also. Your plants look really good so just watch the shade of green in your leaves and zero in the ppm's. I try to keep a nice, solid, dark green color. If they are lighter green they need more nutes. Also keep those pots wet in bloom. Your trics will dry out and disappear if the pot dries out too much.

My tap is now 380 and I have had issues with it in the past so doing a mix to 120 tap/RO has worked better this time.
I just made a mix of 28g RO and 8g tap for 120PPM then 103g jacks citurs which is just under 3g/g to the 36g total for 470PPM. This is for veg. This batch came right out at 6.0ph which has never happened before as usually close or above 7. I will leave it at 6.0.
I will work on zeroing in PPM for color of leaves.

My new Jacks Citrus looks more light blue than the dark blue and when mixed with water it is green rather than blue. Weird.

purchased when? serials, label changes that you can distinguish any marks showing the batch date? i saw the changes in terpinator a few years ago, none for the worse but still changes, they upped the dosage to empty the bottle faster, cant fault them though, thats business...

So you're saying Jack's is of lower quality? I remember you saying a while back that hydro gardens had more micro's in it than jacks even though they have the same n-p-k ratio, does that mean you would feed any differently with jack's as opposed to hydro gardens?

Yes. With hydro-gardens I have no need to add micros.

The basic ratios remain the same.

Not sure if that worked, on my phone. But here's a direct link.

Ok so the issue there is the nitrogen and potassium in there along with the micros, they'll throw your ratios off.

Unfortunately the liquid nutrient makers love to play this game to force the user to stick with their whole line of products.

Once you have an idea about how to use dry nutrient salts, you could use this and skip the calcium nitrate in your solution... But by then you'd realize that's still more expensive than just using the dry nutrients by themselves.

If you saw the ingredients on the label of the Mineral Matrix, you'll see that it does not contain much NPK at all, just 1% potassium (K). That's why it's such a good micronutrient supplement.

Again, with Hydro-gardens mixes, it's just not needed.

have you thought of using the acid special along with the citrus? the acid special has 14% sulfur, citrus has 5% i think, and the hydrangea has 9%. i think i am going with all three combined in increments on the next go round... maybe even aquagold with its 9%...

Im not sure what that is. I'm not really good at this. My room is so small i crawl around in it to water so can barley see plants to read what they want assuming I knew how to tell. I just read on here and follow. Was thinking of getting Aquagold but have to buy from reseller only and was $61 shipped so went with 1lb K2SO4 for $5 for now. I may get the Aquagold for next time.

Sweet I can actually access mineral matrix here. Roughly how many ml per gallon, or litres preferably, would you recommend with jacks hydro?

I think you mentioned a 3-2-1 ratio earlier (jacks, nitrates, Epsom). You then adjust your EC

Where does the micro nutrients come in. Do you make your mix, then ec, then micro, then ec again? Sorry if it's simple I just can't get my head round that part!

I would also like to add some silica and sometimes rhizotonic and cannazym.

And do you run the same amount, of the micros, start to finish or are more elements used in late flower say?

I'm going to try read more on it, but this thread has been the best resource I've come across. Maybe someone can share other links?

Add rhizotonic, cannazym and say silica at my preferred measurements to my nutrient mix. Also my micros, mineral matrix say.

Then add a concentrated jacks 3-2-1 ratio to bring my ec up?

Think that's it. What measurements of micros would you recommend?

Hoping it's low at 30 a litre lol

I used 2 ml Mineral Matrix to 5 gallons of plant ready nutrient solution. That's only because Jacks is short on iron and micros as a cost saving measure.

That's really why I recommend hydro-gardens. They aren't scared to talk about Cannabis because they're based here in Colorado. Bonus!

I just use 3-2-1 and nothing else and it works like a charm.
