Critical Jack Auto Not Flowering at 7 Weeks

so my critical jack has been growing for 7 weeks now and still only pre flowers the plant looks healthy but some dying off leaves at the bottom and i've under watered it a bit and it might be slightly too hot in my grow room but other than that fine, what should i do to get this auto flower to start flowering ??

conditions play a part as does size

Some auto`s take a fully 12 weeks to bloom fully some people call the slow auto`s other people who can ID them early and get them the extra root and growing space call them "super auto`s"

I cut down a few auto`s the other day as they were really really ripe but one plant was bigger but lacking in development that plant is staying up 2 to 4 more weeks and is getting fatter already should double the yield I was getting off the others

Hard as hell to tell without full set up info and pic`s of the plant but stick with it.

How much light is the plant getting and for how long per day ?

using a 250w hps 11litre pots and 18/6 light cycle

Hmmm no reason for them not to flower

I use 11L pots and you can get anything from a half to 2 oz per plant with most auto`s at the power level

I`ve run auto`s under 18/6 20/4 and 24/0 but they do flower a bit more if you drop down to 16/8 or even 12/12 you just start loosing any extra veg that would have happened.

You have 3 options if your feeding and watering is spot on now

1 leave it be and let it finish

2 dial back your times to 14/10 over the next week

3 get some more red spectrum light onto the plant`s that are being slow, CJ normally does really well under 630nm hence lot`s of people with basic led set ups like using CJ

if your at 18/6 your plant will never bud. your photoperiod has to be at 12/12 to start the flowering process....

sorry didnt see the auto part.....duh....to many joints!

Someone else had this issue with Critical Jack autos too. Switched to 12/12 like a reg and it flowered I believe.. Is this one plant or several?

its one plant but i have a LA confidential plant vegging in the same area as the auto so i dont really want to turn it to 12/12 as i dont have much space

14/10 seams worth a try then or maybe 16/8

10 hours of dark should not flower LAC but 10.5 hour of dark is around the min where flowering starts to be induced on most strains I guess.

I had an auto not flower under the 18/6, after maybe 6-7 weeks I flipped it to 12/12 and it flower and yielded pretty good too. Other autos that came in same pack I had no problem with

thanks for the help , think i'm going to go with 16/8 and if i don't see much improvement after a couple weeks 14/10
