i use 10-10-10 fertilizer the granular kind i mix it in water and let it stand for a day or two and then give it to my plants and ive had good results i use color for strength dark is stronger light is weaker anx i give the darkest to my inground trees and big containet trees and light to my rooted cuttings ive noticed faster growth that isnt leggy on most plant i stopped using mg weeks ago so the effects should have worn off and since using the 10-10-10 ive seen better root growth and foliar growth
