Proper method for fertigating a planter

[TomH]

I’ve always wondered when fertigating a planter and the larger the planter, the more of a question.

This is irrespective of the type (veg/flower) as well as strength of nutrient solution.

Do you:
1) water, fertigate, water?

2) Fertigate, water?

3) Simply all the liquid on feed day gets nutrients?

It always seems like the first method would be best, hydrate the roots, add nutrition and a drink to finish off the meal.
But, is that the best process?

It seems like the 3rd option introduces the possibility of over fertilization.

Enquiring minds want to know!

Both of us are in Autopots and feed through a reservoir with water lines. I feed about what they say on the label every feed with a full line from General Hydroponics flora 3 part + other additives as needed & Epsom salts every feed.

In soil only grows/promix I was feed /water/feed/water ect. but there are times you can back to back feed as they grow if they appear to light in color
