I stand corrected .... one shot even tho it has nitrogen in it is protein nitrogen , not nitrate , ammoniacal , or urea nitrogen like in syn ferts ....... you need proteins to build soil buds . calcium , phosphorus and protein nitrogen (amino acids) builds buds and pack on weight .. you"ll actually lose yield if you cut out all nitrogen ...so , how much to use ? soon as planted in pots (rooted) clones , 1 cup per 5 gallon ....30-45 days in veg , I flip and give the day 1 of bloom one shot dress ( 1 cup per 5 gallon ) this is using cultured teas .. and no bottle....
