Sure! Let’s first define what a veg ratio is. Within the context of salt-based ferts I think Jacks 321 is a good “gold standard” veg formula for inert mediums.
I plan everything I do around the N number. Jack’s suggests that 150N is appropriate through veg. The lowest I go is 120N which is actually, simply, Jacks 321 at literal 3g Hydro, 2g CalNit, 1g Epsom. This is an 80% strength (120N) blend that I personally use in veg to grow out smaller plants. The 100% strength (150N) formula for 3-2-1 is ~3.79g Hydro, 2.52 grams CalNit, and 1g epsom.
Jack’s provides a nutrient schedule for 0-12-26 that you might find interesting… because it still implicates the 5-12-26 for veg (and employs 0-12-26 only for late flower):
So that all said, you want a 0-12-26 for veg. You want micros to be similar to that of the 3-2-1 program with the lowest concentration of micros being equivalant to an 80% strength mix of original 3-2-1 blend (120N).
Here’s a 120N blend using 0-12-26:
Per Gallon:
- 3.8g 0-12-26
- 3.0g CalNit
- 1.2g Epsom
We’ll call this is 19-15-6 Blend
