Went ahead and ordered some. Will be very interesting to compare.

Awesome! I just started it in my DTW feeds a couple days ago. It’ll be nice to see how it works in your setup too.

It looks like that comes from MAP in their ingredients. It’s not desirable, but it’s in a pretty small ratio when you mix the calnitrate, so it shouldn’t be a problem.

Hey man, I’m just placing my orders for my coco adventure and just thought I’d give you guys an update. The place that sells Masterblend sells it as the following package:
- 200/400/600/800 gram Masterblend® 4-18-38
- 200/400/600/800 gram Calcium Nitrate
- 100/200/300/400 gram Magnesium Sulfate
Now you’ve mentioned that for veg you’d swap out the epsom salt (mag sulfate) for magnesium nitrate… So I ordered that as well!
Let’s hope the postman keeps on truckin’ and gets here soon.

I think the Mag Nitrate is very nice to use in veg. My formula is slightly different, but I am curious how their recommended ratios work out. The only difference is that I use more epsom. I am wondering if they only recommend 400 epsom, because it is a soil/hydro formula.

I’m using the MasterBlend mix right now (coco coir in flower) at:
25g MB
24g Cal nitrate
23g Epsom
One of my plants it showing calcium deficiency… but I’m also changing a lot of things right now. 6x feeds per day & EC dropped to 1.3. I’m in a difficult spot trying to balance growing nute-sensitive pure sativas and nute hungry pure indicas. I was feeding at 1.6-1.8, but the sativas complained. Overall, I’m trying to use lower EC and higher feed rates, due to moisture problems with higher EC and lower feed rates in my small 1 gal pots…
Anyway, based on the fact that calcium deficiency is the first sign I’m seeing, I’m going to try dropping the epsom in the mix. I think I’m at about 2:1 right now. Might try more like 18-20g instead of 23g next time.

Jacks 321 is hard to beat.
And as you say different water makes the formulas different for everyone. 6.8 is my sweet spot in coco. My tap is 5.7.

Yeah keep hearing so must be the dogs 
you in uk ? You used any off the above ? Most ? All? Any chelts in the tank ? Micros ? Ect?
My tap is ph 6.0 50ppm from the tap
I have used citrus and Jacks 321, I’m in the states. If you’re in the UK shipping may put Jacks products out of your reach due to shipping cost, but I really don’t know.
Megacrop has a distributor in the EU if I’m not mistaken.
At any rate I’m sure you have options similar that’s produced in UK/EU just under other companies names

I have been happily using Jack’s Citrus FeED for about 7 years or so now.
However I do not use coco, I use soilless mix (ProMixBX or HP).
Citrus FeED has 4.9% sulfur, but it is a little skimpy with Mg and has no Ca, this is not a problem for me because I add a little dolomite lime to the ProMix.
Hat tip to Uncle Ben, wherever you are!

If you ever go to coco, or coco mixes, this is what makes it unusable. If it’s already a little light for soil, your plants will scream in coco.

Yes indeed, I even hesitated to post in this thread, because it is about the Coco Experience.
But, I wanted to give a shout out to Uncle Ben.
