Hi all, 

 

I was wondering if any member has input on how to calculate N-P-K  ratios. Most fertiser companies provide a generic feeding chart for the various stages of growth. Various strains consumes differently and I am currently experiencing that.

 

I want to understand how to calculate the ratios to optimise the best possible feeding for my plants.

 

I have read that the ratios below are optimsed for the various stages of growth.

 

VEGETATIVE:

Seedlings 2-1-2

Early Vegetative 4-2-3

Mid-Vegetative 10-5-7

 

FLOWERING:

Cycle Changeover 7-7-7

Early Flowering 5-10-7

Mid-Flowering 6-15-10

Late Flowering 4-10-7

 

Using Nutriplex Trio as an example.

Micro 5-0-1

Grow 2-1-6

Bloom 0-5-4

 

How would I adjust Nutriplex to achieve the various ratios.:investigating

 

If someone could help out with the formula, it would be highly appreciated. :poke

 

Ill use the formula to setup an excel sheet to calculate.
