rhodes68answered grow question 5 years ago I did this last summer on an outdoor grow, yes you can but I really could not see much difference over a alternating schedule.
Lot determined by how fast you dry out, every three days means your plant gets fed about once a week, two days means about 2 times a week-ish.
Have to remember the organics do not act on the plant as much as they act on the soil so a good feed once a week aint bad, two would be better IMO.
I know you want them big and beefy but organic just has a bit different aspect over mineral.
Long as you have no deficiencies and growth is good thats about the best you can hope for is it not?
