Should i start flushing this autoflower?

On day 74 of this Royal Queen seeds nothern light auto. According to what ive seen off other growers is that there is about 10 days left however there is no yellow leafs some buds look under developed this is my first grow and am unsure. I am doing a stealth grow using CFL 150 watt dual spectrum. Am using London grow micro, grow and bloom 3 part base nutrients. I also have been using high phosphorus bat gauno and some tomato feed

 

I also forgot to mention i did not use perlite in my soil i instead accidentally got vermiculite (my first grow) and it wasnt until the seed was planted i read into perlite and found moreless every soil grower uses it over vermiculite however my plant still flourished without perlite for drainage am however using a fabric pot aswell for aeration. Thinking thats how my plant has survived the damper conditions. I am also using apple cider vinegar for my ph down and kept it between 5.5-6.2 with my ph up being baking soda.
