Well they have been flowering for 13 days now. according to the strain they should be ready in about 6 more weeks, but i got a 30x magnifier i am going by also. I am going to wait until the tricombs are slightly amber in color before i harvest. I ordered the fox farm trio pack. with grow big, big bloom, and tiger bloom. which of the three should i use. i don't think i should us all of, i am leaning towards the tiger bloom, or the big bloom. i am probably only going to go 1/4 to 1/2 strength dosage also. well here are some pictures of my babies. i think the northern lights will be ready before the white rhino. let me know what you think, or if there is something you guys see or notice i should be doing. later. keep growing.
