This is the deal, if I've read correctly. They specifically mentioned that anything shipped after like mid-August (can't seem to find the exact date now) was v3, although for a bit it may be in a v2 bag. (Waste not, want not, it seems.)
I can see the deal from both approaches. On the one hand, a single item to measure and mix can be pretty handy, however you want to do it. Trash can, mash stick, dump and stir. Once it's whirred up pretty good, run a little circ pump to keep it stirring for a bit.
The simplicity cannot be overstated. Add X per gallon/liter, and that's it. Follow it, watch your plants, and see if/when they want more or less.
It also seems that they've put out a feed chart that (gasp) is right about where it needs to be to start. With the reported ppm's being even a bit lower than what a lot are running. So it wouldn't seem that the typical "cut by half" method for other nutrient lines would be necessary. Again, simple.
Now the other side, it where yes, advanced growing comes into play. That's why lines have multiple products. The bases will get you there, but as you broaden your experience you broaden your awareness of other additives, what they do and are for, and how to use them.
Take the tried and true GH Flora trio. Those 3 bottles have put out a LOT of good weed over the past several decades without anything extra. However, with more advanced knowledge you can even refine that process and get even better results.
Are there companies out there that specifically will be very underwhelming with just the base? Absolutely. Do your homework first; it's that simple. If you want simplicity, go for it. If you want to be a complete control freak because you want certain levels of this and that precisely, well there are companies that have you covered as well.
I like the ability to choose. Even Greenleaf sells the pieces to MC individually. No shame or harm in that. The more of an audience you can cover, the more people that can use your product.
I will say that about $75 USD (w/shipping) for 2500 gallons of nutes? That's 3¢/gallon and you can't beat that. (Of course the 2500 gallon mark is probably at the lower level of feed, but even if you get 1500 gallons through all phases, that's still a damn bargain.
I'm set for nutes on my next full run already, but I'll be keeping an eye on the results coming out from just using straight MC with no extras (calmag excluded) and seeing how it goes. I would say my biggest fear is on my coco system and maybe clogging drippers (if it didn't fully dissolve) but my RDWC wouldn't be an issue at all.
. No, definitely none of that, but I have the two previously mentioned products for P & K and K supplementation. And multiple partial odds & ends. Will likely be able to play mad scientist, no worries.
