Most should state something like Hydroponic or Solution Grade. If you see one pm me the product and I can search it out and get the info on it.
If it says hydroponic though that would mean it’s made for retail sales right? Hence such a rip off

No that's if you buy stuff in a hydro store or promoted for hydro retail. Jacks says hydroponic on several different blends. Hydroponics is gonna mean nutrients that are delivered mixed in water. If a 5lb amount of powdered nutrients costs as much as 25lb of say Jacks that catering to retail hobby hydro. No there is nothing wrong with it but there are much cheaper alternatives. Most hydro stores wont push powders as there's very little money in it. In store I'll make $20 dollar on a bag of Jacks which will last a customer a few crops or a whole year vs them buying a set of GH 24L every crop or couple times per crop. No mind you Vancouver/Coast are of BC is brutal for profits in hydro stores as there so much competiton. There's probably like 30 stores in the greater Vancouver are with 2.5-3 mil people vs Calgary with 5 stores with 1 million people Hell in my town where my store is there's 3 stores for 40K people. So a hydro store wont promote them.

I see it as the customer will save money and then spend money on better equipment and rooms set up which will get them bigger yields which will mean they might spend more in the store.. They will still end up buying some additives anyways.

So,
ive spent hours and hours searching through local suppliers for a good powdered nute.

ive found this:

Solufeed Strawberry Special 20 kg


Total nitrogen (N) 2.2%
P2O5 (P) 9.2%
K2O (K) 29%
MgO (Mg) 8.9%
Boron (B) soluble in water Copper (Cu) (EDTA) 0.03%
Iron (Fe) (EDTA)
Manganese (Mn) (EDTA) 0.17%
Molybdenum (Mo) soluble in water 0.008%
Zinc (Zn) (EDTA) 0.14%

really good price on it too.

would this work good with calcium nitrate to control the N?

id probably use magnesium sulphate and calcium sulphate for a decent amount of magnesium calcium and sulphur .
or my concern is that this mix may have too much magnesium?

I ran out of MC 1 part and have been using the 2 part for the past couple weeks.

My notes comparing MC 1 part to the new 2 part so far:

Pros
- 2 part is waaaaaaaaaay cleaner than the 1 part for hydro. Theres still room for improvement to be cleaner for hydro but it is much more hydro friendly than the 1 part. It has some small slithery residue pieces when I water change but not a big deal.
- 2 part mixes much easier than the 1 part.
- 2 part is pretty clear in reservoir... still has a peach color to it but clear overall. My buddy says Jacks is much more clear and it doesnt have that slithering residue at all.
- Can tweak the NPK for what nutes you need for the

Cons
- Gotta dump 2 nutes instead of 1 with the new recipe so double the work.
- Somehow smells even worse than the 1 part. Made my room reek for a day or two even with the carbon filter on. I wanted to throw up the first time I opened the bag but its not as bad anymore since Ive gotten used to the smell.

MC 1 part did fantastic for me. If this 2 part gives me the same yield and quality. easy winner.

My only problem is the nonsense recommended doses for both MCs. Both versions....I got deficiencies following the recommended amt.

People said the recommended dose worked for them but not in my case. Ive bumped up the dose so far and I think its stopping the deficiencies.

Version 3 of the 1 part is much different looking than version 2

Ya I've got both DE and the LED gavita's. The led ones are pricey but superb imo. I understand why it's a hard sell. I've been trying to convert over but it's hard at that price. I think I'd go LED only if it was the Gavita's
I got 1000w de gavita hps right now but im saving up and leaning towards changing my whole setup to Gavita LEDs because of the even spread and less power and better spectrum.

Hows your yield when u compare the Gavita DE HPS vs the Gavita LED?

ahhh i see. Looks exactly the same as their part A in the 2 part.

dang it. if i knew..... I wouldve went with the 1 part cause its less work lol.

Only benefit of the 2 part over the 1 part I see now is tweaking the NPK to your choosing depending on what week youre at. I dont really believe in what people say increasing P and K makes the buds bigger and potent etc. Ive grown good weed with Dynagro's Foliage Pro 9-3-6 NPK from clone to harvest. the P and K is pretty low in it for flower but I didnt see a difference in higher yield or bigger nugs etc.

I think they are very close. But in my setup I get overlap from the the LED's and the HPS's. Your correct the heat and hydro are big factors and worth investigating vs cost to get there. In some spots my girls get more LED now due to a reconfigure I just did. They love the leds. I just added another controller to operate the HPS ones separately from the LED units. So it's two systems now basically. At this point I'm not planning on changing much. Maybe add one more Gavita Led. I've done a bunch of changes lately to get a better swing. Amazing what I can think of when I just sit in the room and think and look around. Then I think to myself you stupid fucker, what took you so long to think of this or that. I'm tweaking the room to the max. Too much work though...lol

Is this bro science or are there actual scientific studies saying that you should tweak the NPK depending on what stage the plant is?

Because I used MCs 9-6-17 NPK 1 part last run from clone to harvest and had very good results despite the high nitrogen late in mid to late flower. I did add a bit of Bud Explosion after they started budding but I kept my MC doseage the same throughout the whole flower stage.

Ive also done Dynagro's Foliage Pro 9-3-6 from clone to harvest with no PK booster and it was a very good run as well. I had no phosphorus or potassium deficiencies

Many nute feed charts vary NPK ratios for the different stages of growth.

Many growers use the same NPK start to finish.

I have been using the 2 part hydro formula for a couple of weeks. All in all it's been great. It's embarrassing close to Jacks 2-part but, I don't feel like I am getting robbed in the end.

I am just starting to turn the dial a bit in veg. I started out with the recommended dosage of 1.5 g/gal Part A and 2.5 g/gal of Part B which was decent. I did however find them lightening up a little so I added another .5 g/gal of Part B. Now I see some tip burn starting to appear slowly. Any suggestions on where to go. Currently I will be dropping the Part B back down to the 2.5 g/gal mark.

How's everyone liking the new formula of Mega Crop. Anybody seeing any differences?
I would like to know this as well. The old version was excellent for vege through to the end of stretch. With a few tweaks.

Be nice to know if they have removed those tweaks needed.

I've almost run through a 10kg bag of the the last version.

I have been using the 2 part in my hydro set up for over a month. The plants are happy with the mix. I don't see much difference in vegetation compared to other versions. This new mix is by far cleaner when mixed, stays clear and dissolves fairly quickly. I do have the one part and it looks to be identical to the 2 part just premixed with a couple goodies mixed in. I would also note when I mixed the 2part with RO water I haven't had to adjust PH. Its pH stays stable for quite awhile in my mix bucket.

I like it way better than the last version. Rez is crystal clear. Last versions looked like a pile of dogshit if I didnt change it out after 2 weeks.

Ive been using the 2 part for the last 7 weeks in my bloom and I like the results.

I ordered another 22lb bag yesterday but the 1 part this time.

Im planning to use the 1 part for veg and 2 part for bloom. Im also thinking of using the 1 part in one bloom rez and 2 part in my other bloom rez and seeing them go toe to toe. If its the same end result... why do twice the work?
