Don't bother with their chart. Just find someone who has been doing it a while and use their recipe. That's where I got this one, I didn't invent it. Omit the green bottle.
Photosysnthesis plus per instructions (you can skip this altogether of budget is tight)
Orca per instructions. (don't skip)
GH Armor Si 5ml per gallon (mix per instructions, very important)
GH Cali-magic 5-8ml per gallon (see where the plants like it)
GH Micro 8ml per gallon
GH Bloom 16ml per gallon
Botanicaire
Liquid Karma 5ml per gallon (you can go to 8ml, but try it in a year when you are more in sync)
I would measure that out and take a reading and see where you are ppm wise. I've been using it for quite a while so I don't bother anymore (and therefore don't remember).
Then dilute it to where you need to be at. In the future, you can scale back the Micro and bloom to be where you want to be, but I think it will be fine. Leave the rest as is. In other words, don't go lower than 5ml per gallon on Armor Si or Cali-magic or Karma.
I believe it's the
Liquid Karma, but even with pretty high ppm, growing plants seem to take it and love it. You might tweak a couple things here and there, e.g. I added photo plus bc I find it makes the plants stinkier and faster...but that exact recipe above is used by several breeders and long time growers. I would just start using it asap and forget about nutes for a while and work on the environmental issues if there are any. When you start it, dilute it and make sure your plants like it. No reason they shouldn't, but some plants are light feeders.
Also, bc the plants don't show signs of stress or burn doesn't mean the mix is appropriate. I wouldn't go higher than 1000 ppm peak for your first time. Feeding higher is walking a fine line. For your first couple runs, it's not worth the risk imo. You will slaughter at 1000ppm with the above recipe. 1200 won't be better your first time. It's the type of thing you get a feel for with time.
If you overfeed with the above recipe, they don't usually show signs of burn, they will become mutantly large and you can have problems with bud rot etc. So you have to be concious of it. But if you want a framework to build off of, there it is. I've messed with it a great deal since I got it, and I always end up coming back to the way I received it every time.
Also, the way I received it had GH Liquid Koolbloom at 5ml per gallon. But others were omitting it and didnt notice much, I tried it as well and didn't notice a difference. So now I just add it weeks 1-4-ish of flower. But that's a line you don't need to walk just yet. But fyi, that was part of it.
