Liberty Haze/ soil/ led Cob

Your good👍 As long as she had more then 12hrs of light it shouldn’t trigger flowering. Next time this happens if you are aware of it at the time you can add some high power flashlights over them to keep the light going. I actually have a UPS backup power supply bar on both my tents that power all my pumps for my RDWC and also a couple of lower powered compact led lights that I can power up off them in the event of a power outage. Always a good idea to have a power backup of some kind for just these occasion. Cheers💨

I wait til i see the first sign of pistils before introducing bloom nutes. I use green leaf bud explosion using the K.I.S.S. Method ( keep it simple stupid) not saying that to you. Lol

Pre-flower stretch usually lasts about 1-2 weeks so you're probably nearing it's end (considering she also doubled her size). if she still rapidly stretches you can try more tying and spreading for more lateral growth, it might be difficult with the limited space you have so be careful! Super-Cropping is a HST (High Stress Training) which means it'll cause immense stress on your plant and may stunt growth for a few days before it becomes beneficial, this may be manageable while in veg but when flowering it most likely will harm your plant and diminish yields. I do not recommend Super-Cropping after 1-2 weeks before flowering is induced!! You can also check my Super-Cropping experience in my Diary and get an idea of what it is. Hope this helps! Good luck and happy growing :)
