if you use granular nutes you give away any control you have...if you over feed you're fucked...how will you flush?
you gotta be rich if you want to use AN nutes outdoors...it would cost like $800 for the full line and they wont last the whole season..(i have done this...it was a mistake)
i will never buy another AN product...they sell snake oil...
now,i use maxsea outside...i have also used jack's classic in the past....i liked both... they should cost less than $100 (idk garden you garden's size) for the whole season...
i feed a 5 gallon bucket to each plant (in 100 gallon smart pots) once a week...
when they start to bud use half grow/half bloom for 2 weeks
good luck....
i even started using maxsea inside...
