I've been using AN for 20 years. All I buy is the 3-part for my base, Big Bud for bloom and Rhino Skin for DWC. Growing mainly in ProMix HP these days. Any old Calmag will do and of course some Epsom Salts here and there. I do not read their feeding chart.
The 3-part with the Gorilla in the label is a different formulation than the older style and I saved an explanation I typed up in another thread.
I've been using AN 3-part for 20 years. I bought gal jugs about 5 years ago and just now noticed that the N-P-K ratios have changed but I've been using it just like the older stuff that has the same ratios as the Jungle Juice and the GH 3-part. This may explain some of the problems I've seen in flowering especially when I switch to Lucas Formula feeding after the stretch. I have 1L bottles of the older pre-pH Perfect 3-part and dug them out to check.
Old AN, JJ and GH are Grow - 2-1-6, Micro - 5-0-1, Bloom - 2-5-4
This 5 yo AN 3-part is Grow - 1-0-4, Micro - 2-0-0, Bloom - 1-3-4 (Has the Gorilla on the jugs)
Totally throws thing off to what I had become so accustomed to. I'm going to have to sit down and reformulate some of my mixes to be feeding each nute at the same ratios I was before. Much more diluted now too. With less than half the N as before it throws the Lucas feeding way off. No wonder the old leaves yellow out so fast and early.
I also have some REMO nutes from winning a 7 - 250ml bottle kit in a raffle at a hydro store I deal with and their ratios are different again.
G - 2-3-5
M - 3-0-1
B - 1-4-7
Seems to work OK mixing about half strength at 2ml/L and I never check pH so it's still good stuff.
