Auto flower didn’t bloom

Hey Folks, I need some guidance on an auto flower that did Not flower.

it’s a THC Bomb Auto, it’s halfway through week #4 (26 days).
24/0 light schedule
It looks like it started to bloom around day 23 but then it stopped.

my question is, if I put the plant on 12/12 lighting to trigger the bloom cycle, would I need to continue running it 12/12 all the way through to the end, or once it triggers can I put it on 24/0 ?

Ok, I’ll wait a little longer. This is my second Auto ever. The first auto bloomed on day 22.
is it normal for an auto to take around 35 days to bloom ?

Autos will flower when they are mature enough to do so. For the most part.

I have an auto right now on day 55 with no hairs. It is about to ender the stretch phase.

I snapped the root on day 3 or something and then stunted it with light.

So your probably fine.

I'm running 4 autos right now (2x Northern Lights, 1x Blueberry, 1x Tangerine Dream) and I just checked for you...First signs of pre/flower were at days 31-35 from dropping the seeds in the ground. If you want count above the soil days that was 34-38.

Thank you, very much.
Do you decrease the nitrogen when you enter flower or do you increase the bloom nutes?
I ask, because I found a GH auto flower feed chart that just seemed wrong.

Which chart is that, the 420Fastbuds one? I've fussed with a few across this grow and ended up back at the GH 'light' trio chart at half strength. The GH one does drop the Micro (nitrogen heavy component) back for flower and flexes the trio throughout the grow to match the plants' needs (roughly). The Trio schedule chart shows a PPM range for each feeding week along the way, and it seems pretty accurate, given what I'm getting for half-feedings for auto flower.

At the week 10 early/mid flower range I thing they list 4.6ml Micro, 4.6ml Grow, 6.6ml Bloom. So mine is 2.3, 2.3, 3.3 per gallon. It was giving me a total of ~650ppm with the 220ppm water I have. I did move to Flora Micro Hardwater though and it dropped that 650ppm down to 500-550ppm, which I think is still solid.

Yes, it was the 420fastbud chart.
Thanks, your response answered all my questions
