[@pn3940]

the reason you dissolve the green one first because that would help the calcium nitrate to dissolve faster. if you mix the calcium nitrate by itself you're going to spend a lot of time stirring it to dissolve.

[@CBsGreenhouseandGarden]

This is so funny to see ya showing how to mix it the correct way. Master Blend contacted me a few years back which I done a video on that. Anyway the one teaspoon came from my recommendations so they printed it with out no reference back to me or my channel. Oh well been preaching it for years now that the amount of grams that has been shown for many years was not the correct amount. Just another kick in my butt and failure to my channel. Glad to see a top notch channel like yourself do a video like this to help all the folks that were taught the wrong way. Stay safe and have a great weekend down there!

All this time (about 2 years) I have been mixing the Masterblend/epsom salts/calcium nitrate according to the instructions on my bag of MB (2tsp of each). I just went to the MB website to see if they have updated the ratios, and sure enough they now recommend 1.5-2tsp epsom salts. When did this happen??? I have been having good results with the original ratios, but can I now expect better results when I do it correctly? I'm really glad I ran into your comment here, thanks for doing that!

Thanks for the video. I tried growing some of my alfalfa sprouts to the full plant hoping to eventually get some seeds; however the sprouts dried within a week despite the fact that their roots were always in the nutrition medium and they all started looking healthy. I suspect that they "burned" by the amount of fertilizer in the solution. I will try diluting it even more in my next try but I wonder if you have ever tried this and have a special recommendation. Thanks again!

[@mytech6779]

Wrong nutrient blend, legumes prefer ammonium to nitrate. Ammonium is what their root nodule bacteria produce when field grown.(No nodules in hydroponics so all N must be supplied. The nodules also require extra elements like cobalt not found in normal fertilizers, not even hydro blends)

[@johnschulenberg1]

Would to ok to grind the epsom salts finer to help with it dissolving faster?

[@coastaldirect]

What I do is mix the Masterblend formula in a small cup of water, like those little bathroom cups, plastic ones and stir it with a small stick or wooden dowel. Sometimes it even helps to nuke a larger cup of the water in the microwave for a minute and poor it into the smaller cup so it disolves faster when stirred. Then I poor it in the bucket and stir a few times. Same for the Epsom salt next and then the Calcium Nitrate. 10-10-5 for leafy greens like lettuce and micros and 12-12-6 for vine plants like Tomatoes. Simple. Disolve first in a small cup and stir until disolved and then poor into the bucket. This is by far the most effective way to mix nutrients with absutely no effort and I can't believe nobody does it this way! Lol C'mon people, innovate and don't make things so darn complicated. Love your videos though. :) Good luck with the course.

[@francoistran5681]

Can you please explain how to make 10-10-5 and 12-12-6? I am new to Mining.

[@coastaldirect]

@@francoistran5681 Okay...so You have your Master blend formula that's green color, your epsom salt and your calcium nitrate which are the little pebbles. Always mix your Master blend and calcium nitrate at the same ratio and the Epsom salt is always exactly half. Now for 10-10-5 what that means is that you are going to make a lesser concentrated blend per gallon. It's a 5 gallon ratio so 10 grams master blend for every 5 gallons of nutrients, 10 grams of calcium nitrate and only 5 grams of Epsom salt for 5 gallons. 10-10-5. If you wanted to make 1 gallon instead of 5 it's easy. Just divide the 10-10-5 by 5 gallons and you get your per gallon ratio. In this case it would be 2-2-1. Now if you are growing peppers or tomatoes you probably want to up the concentration to the 12-12-6 ratio for 5 gallons. So for one gallon it would be 2.4 - 2.4 - 1.2 grams. Now always mix your nutrient in a small cup of warm water first and then poor it into the container with at least several cups of water already in it to avoid calcification. Don't mix the nutrients together until they are completely blended in each cup and disolved. You can make any size batch you want as long as you make sure you know how many gallons of nutrients you put in your original jug and you divide it out equality amount the gallons you want to make. If you still have questions let me know. Oh and also follow this order. master blend first, then Epsom salt then calcium nitrate. Don't ever mix your nitrate into the solution before the other two. That's it.

No idea what Coastal Direct is saying. I don’t understand any of this mixing and ratios. Why does Mike show the cap that says how many cups etc per gallon when that doesn’t apply to these ratios?

Can a solution be poured into ice cube molds, frozen, stored in foodsaver vacuum bags for freezer storage ? Does freezing destroy or weaken the solution ?

- Instead, can one just buy the premixed 4-18-38 salt/nutrient blend? Or is there an advantage to buying the pre-blends separately? - How often do you replace the nutrient solution? Thank you!

[@KeepOnGrowin]

The calcium nitrate has to be kept separate, it absorbs a lot of moisture. Epsom salt is cheap at a drug store, better to just pay for nutrients and get the epsom salt yourself.

[@mytech6779]

Calcium likes to bond with sulfate to make gypsum which is only soluble in very dilute amounts and is difficult to redissolve so Ca and sulfates should never be mixed in a concentrate, dry or liquid. Calcium and Magnesium can, under some conditions, bond with phosphate in a similar insoluble manner so is ideally stored separate, I have had issues with long term storage of granular mixes. The phosphate issue doesn't seem to be a big problem in stock solutions that are slightly acidic because other elements preferentially bond with the phosphate, but I have only tested solutions with modest P ratios.(eg 13-2-13 with Ca and Mg but no sulfates) The granular issue is likely due to micro concentrations.

[@Metqa]

I made the mistake of trying to make a concentrate in a small amount of liquid. Once I added the calcium, the liquid turned bright yellow and crystals started to form. No matter how much I shook it, the crystals would not re-dissolve and the plants did NOT like it. I do not recommend making a blend to add all at once and to make sure your solution is dilute enough so that it doesn't want to form crystals and lock up the nutrients from the plants.

Can we use masterblend npk for all plants

[@KeepOnGrowin]

Most leafy greens. I also do with tomatoes and peppers.

[@angiemarriott]

My blend came out at 7.5 and my system needs to be between 5.5-6.5. Do you have a suggestion what I should add to neutralize my mixture? Thank you

[@davedave3631]

Use some ph down, it’s more stable than acetic acid (vinegar) or other home-type options.

Hi Mike, How/where do I sign up for your course?

[@KeepOnGrowin]

Hey there! Here is as link to the playlist. kzbin.info/aero/PLk4IGbDM3vfqQ1k9IiiijcU_uYkfgjR_g

[@padysrini9955]

I have ordered 4-18-38, epsom salt and calcium nitrate. Can someone use litres/gms and give the ratio of water to the 3 chemicals ? Appreciate it. Thanks

[@swampysanta5445]

cal nitrate 0.64g masterblend 0.64 grams and 0.5 grams epsom salt for 1 liter water for 125ppm n 50 ppm p 200 ppm k 121 ppm cal 64 ppm s 50 ppm mag

[@PappasTube1]

can you use this master blend for soil gardening?

[@KeepOnGrowin]

Yes, the manufacturer says it works for both

[@erikmacedo3723]

Hey Mike how big do the micro greens have to be? If they are too small will they die ?

[@KeepOnGrowin]

Up to you, I get anxious, lol

[@lucygomez5586]

How do you mix the bag I purchased that has the 20-20-20, in 5 gallon bucket 🪣 how much do I put in the gallon???

[@KeepOnGrowin]

If from me, one bag is for 5 gallons. If from Amazon, 2 tsp per gallon.

[@SusanRogersMakingItWork4Me]

Mike, I've never asked, do you use tap water, rainwater or store bought spring water? Also: what happens if Algae grows in the water?

[@KeepOnGrowin]

My first few years of videos was with well water. the last few years has been with city tap water. A little algae is ok, too much will use up your nutrients compete with your plants.

[@Cinnamon-sugar-toast]

Spray the algae with “zerotol “ around maybe 5-10 ml per gallon.

[@johnschulenberg1]

Can you grind the calcium nitrate into a powder or a course grind so it could dissolve better and/or quicker?

[@KeepOnGrowin]

Sure. Sounds good.

[@bcmiller2000]

I dissolved the Masterblend and Epsom salt together, then I added the Calcium nitrate crystals, then stirred everything. I found over a week or two they separate and the calcium nitrate appears to settle at the bottom of my reservoir. It appears to cause nutrient lockout, is this what's taking place? The way you mixed it (dissolving everything first and separately, then mixing together afterward) will that keep the solution from settling out while in the reservoir? I ask because when looking in my reservoir after a couple weeks, I see the white residue on the bottom of the reservoir. TIA

[@KeepOnGrowin]

Yes, give it a try. It could also be the difference in water hardness.

[@bcmiller2000]

Mixing everything separately and then together works for me. Thx

[@highlandermss]

I notice that the fertilizer mix kind of has a scum on top of the water. Is that normal?

[@KeepOnGrowin]

yes

[@michaelschnittker7388]

I use three sepat

[@trablu3392]

How do keep ur containers and pipes from molding with constant water in them??

[@KeepOnGrowin]

Rarely ever see mold. Algae sometimes grows a little but it just a matter of keeping light out.

[@porter20g1]

Do you use a meter to check nutrients and PH?

[@KeepOnGrowin]

Never.

[@diva555sg]

why do they separate the calcium nitrate from masterblend instead of apportion out the premixed pack?

[@KeepOnGrowin]

In larger quantities you can get lockout. Also the cal mag absorbs moisture from the air, everything will turn to a solid block.

[@allangreen8631]

Any option for masterblend in Canada? To my knowledge we cannot get that here

[@truenorthminis7876]

Geckogrow is great and the same.

[@user-si6op6zt7b]

Maybe 1 gallon out in the sun (warm water) to mix the calcium nitrate?
