If you're being selective, yes, otherwise, no.
Does AN base compare equally to GH 3 part base, yes, because they directly copied it.
But do many other companies sell 0.5% magnesium in a bottle of water? No.
When you look at AN for what it is, it's quite clearly a piss take. I mean you'd have to be pretty creative to put together a decent argument to say otherwise.
I think the word "just" speaks volumes to be honest.
You can't minimise the fact that they've constructed their 15 bottle nutrient line to milk growers for every possible penny. It's the whole point of the argument.
It's not even an argument. It's a case of whether you'd rather pay $20 for 0.5% magnesium sulphate or $1 for 100x the amount.
They're not.
I know I'm being blunt here and I hope you don't take this as me being confrontational or rude, but there's just no other way for me to put it. I mean there's no room for me to say it any other way. AN doesn't leave me that room to say ok this additive might actually be beneficial in this way etc... because they don't even tell you what's in the bottle. You're investing in blind hope. Nothing more.
On a complete nutrient line fed at the right levels, I'll bet you good money that it's impossible to tell by eye the difference between one plant given all those additives, compared to another given none.
A plant should be in absolute optimum health on any complete full spectrum nutrient. It's that simple. If it's not, it's because of the inability of the grower to read their plants and provide the elements in the correct ratio to suit it's needs at that specific time.
Some plants will need different ratios of elements, but it's very rare you won't be able to get where you want using your base feeds alone. Very very rare. If it's hard to achieve that with your basic foods, change them. Simple.
I want to see pictures of that cut at the time when you think it needs specifically more magnesium. I will give you money if you can't adjust your base feeds or buy a base feed to cater exactly for it's needs.
The calmag myth is the biggest most out of control issue in cannabis cultivation right now. It's massively massively overused. It's the most misdiagnosed deficiency in all of growing and is almost always something completely unrelated.
Yep - well covered
