As I play with the numbers I'm torn between too much Ca in veg or too much K! Decisions decisions.
This would be my two-bag veg mix, which you would just add water to dilute down for first feeding to full veg:
A: 3.2
B: 1.8g
Won't get you Jenny's phone number but it gets you 113-35-150 with Ca at 90, Mg at 37, and S at 50.
You would just dilute that gallon with water when the plant's younger. For example, mix 1 part of that to 3 parts water at the second set of true leaves, and so on as it grows.
For stretch and early flower I'd go:
A: 3.5g
B: 2g
That puts you at 125-38-163 with Ca at 100, Mg at 41, and S at 55.
Personally I would be adding magnesium nitrate to all mixes, so my veg would be:
A: 3.1g
B: 1.6g
Mag-nite: 0.7g
Early flower would be:
A: 3.5g
B: 1.7g
Mag-nite: 0.5g
And late flower would be:
A: 3.9g
B: 2g
Mag-nite: 0.6g
Those are the numbers I would use for my plants. Doesn't mean you don't have to watch them as they grow though, but you know that by now!
