Will this 4-20-39 be okay in Tupur?

https://hydro-gardens.com/product/420-hydroponic-25lbs-bag/

I bought it but they said hydroponic only on the bag. I have Mag Sulfate and Cal Nitrate to supplment.
They sell a 4-18-38 that is a tomato mix that is fine for soil.

I am not sur why 4-20-39 would not be okay for Tupur. I forgot to ask because I did not see the label warning.

Those NPK numbers don't look good to me. But I've never grown in it or with it. Only saw it last night for the first time in another post.

This is their 420 formulation for MMJ hydroponics. I wanted the 25 lb bag but they were out. They offered to sell me the tomato formula. I bought the 5 lb bag of 420 formulation.

The mass majority of nutes are not designed for what we are using it for. I don't care what the label says! These plants need N even through much of flowering. More than almost all products provide. In the same bottles that are short on N they over due the P. This combo brings yellow leaves early in flower. Generally in the first 4 weeks. Once they've turned yellow those leaves won't be green again.

I'm not running a hydro system. But I'm using 2 products and testing them.
A) 20-10-20 I'm using it at 1/4 strength.
B) 9-3-6 again I'm using it at about 1/3 strength

You'll notice how vastly different your 4-20-39 is from what I'm using. It's not only the ratios that you need to consider. There are other micro nutrients. Some companies such as miracle grow use these other micro nutrients specifically to mess with ganja plants! They won't tell you that. But I've gotten to know a guy who has worked commercially with many nute companies. They know it and they did it intentionally.

Either one of those would be OK as a half-assed bloom booster but not any good for vegging plants. For vegging something along the lines of 20-5-10 would work better. Any of those nutes will work with soil so it's odd they would specify hydro only.

I have some powdered NutriGrow part "B" hydro nutes that are 3-9-27 I tried using as a bloom booster when I had run out of Big Bud and was very disappointed with the results. BB is 0-15-35 with 20 amino acids, 10% S, citric and ascorbic acids and works with hydro or soil really well. They have changed the formulation over the years and it just seems to get better all the time.

Sulfur is the big "secret" ingredient for helping produce bigger buds and lots of resin production. It's pretty hard to overdose with sulfur too tho I'm sure some people manage to. The ascorbic acid is supposed to be good for plants so I crush up a couple of 1000mg tabs to add to 5 gal of water once in a while along with B-Complex, zinc, selenium and B-12.

Our Yoda friend on the forums is using their stuff but he is using their 5-11-26 and he is really happy. He is also supplementing, as I am, with Cal Nitrate and Magnesium Sulfate. He is also using 0-52-34 MKP for bloom boosting. I may check into a bloom booster too.

In my case the N is only 4 but the Calcium Nitrate should bring that up. I will talk to the people on Monday. I will also check with Royal Gold (Tupur) folks. Their email tech support is great.

I used it last night for the first time.

With the tupor mix I bet what you have is fine with the calcium nitrate and mag sulfate.

I am sorry I don't know how much calcium nitrate to add to balance out the mix.

But I am sure someone out there will chime in with a recipe. Or a quick search here should have the info.

Coco is not soil. It is treated very much like hydroponics.

Likely no need for a bloom boost. You just taper off he calcium nitrate to alter the ratio when the plants demand.

The bloom boost over such a high PK nute is why everyone has faded leaves and burned tips and edges.

The hydro nute is designed to be flexible for that.

As long as the nitrogen is around the same as the potassium it is balanced for growing. The. It is just a matter of dialing in your ec.

As the plants switch from growing branches and leaves to only bud you just cut down the nitrates.

Thanks bro. I thought I would be okay because Tupur or coco is essentially hydro with a medium to hold the plants. These forums have some of the best people. 99% great folks and 1% psycho jerks.

I can get pretty psycho brother. But I don't think I am a jerk. Just brutally honest. And the mis-information is doled out like candy here.

You can look at it like soiless I believe. The ph and techniques are kind of in between soil and hydro. It's not like pure water culture as the medium holds nutes and waste. Both of my old caregivers grew in coco when it got popular a few years ago.

I know they grew fine with soil nutes and added cal mag. Coco holds on to those elements so it's important to keep it charged.

Your system should work just as well as long as those nutes are complete. And since they are for hydroponics I assume they are minus the calcium. And that is because if mixed in a resivour and left the calcium will precipitate out of the solution. Greenhouses use 2 tanks for fertigation.

I don't know if they have mag but for coco you probably still need extra. Which you said you have.

Good luck with your grow.

I appreciate brutally honest. I like tupur and think it is great. However, I bought a little 6 space cheapo cloning set up for $30 on ebay. It has the tiny baskets, tiny hydroton rocks and smaller rockwool. It is a little plastic thing like you use to bring two sandwiches to work. It has a small aquarium bubbler.

I have clone domes and also a King Cloner (sprayers water on base of stem of clone).

I thought the little $30 bubbler was a joke after 10 days. I checked it today and that bubbling created some amazing roots. Trying to come up with a tupur RDWC hybrid idea. I love the idea of oxygenation in hydro.

I have seen successful cloners made out of floating Tupperware. I bet it works fantastic.

When we know why things work it is easy to buy or make the right tools.

And isn't there a soil hydro hybrid on a thread here now? I know. SIPS. Sub irrigated planter something .....

It's hydro with a soil buffer. Power goes out. Plant stays happy. I have not looked into it much.

I really like growing naturally in soil mix still.

And there is a guy here who uses air pumps in his soil. He calls it AIS. But his Grow has problems continually and I think it is because the air disrupts the soil bacteria. And the CEC.
