well just my 2 cents but works well for me,you want about a 7-5-5 for veg growth for cannabis,or as close as you can get to those numbers works very well for me,I grow in soil,and for flower you will give your normal feed first 2-3 weeks,The plant has to go from veg to flower this is a 21 day process to go from one to the other considered sexing,even if you are sure your plant is a female it still will go threw this 21 day period and it's last vertical push,,I do not count this toward flower the lights are flipped,but 21 days for the plant to sex,,Then you want to feed a 3-10-10,or again as close to those numbers as you can get,and flower for your 8 weeks or what ever your strain calls for ,some may run a bit longer than others,flush with straight water for your last 2 weeks,,
PS watch giving too much P during flower from your npk,you can actually shorten flower slightly with too much,and anything that shortens your harvest days I do not view as a good thing,,I am cutting mine now tonight as they have had there 8 weeks and 21 days the trics are good and close,here are a few pics I what I get with those numbers,in a small indoor I got those numbers for NPK years back from a cannabis institute,that claims to have been growing for medical and science for over 40 years,they are pretty darn close ,good luck with your grow my friend
