I am growing out a mdanzig autoflowering blue streak and have them under 24/0 cycle for 20 days with fox farm grow big which is 6-4-4 and was wondering could I use something like Age Old Organics Bloom which has 5-10-5 all the way threw insted of using fox farm and then switching to the blooming nutes or would that cause it to bloom premateurly or would it be ok cause it is a autoflowering plant? Also I have added pics below.
