Grow 5 - Northern Light

Hi, I had the same problems with my auto. The issue is that under 12/12 light, it stretches a lot and gets huge. Mine developed flower sites, but after 70 days of flowering, they were neither nice nor big. I suspect that autos aren’t designed for such a long lifecycle and aren’t capable of producing much as large plants. On the other hand, the reduced lighting duration could be compensated with more intense light, but that stresses the plant significantly. My advice: throw out the photoperiodic one, even though it’s a real shame.

Si cambias a 12/12 tus otras automaticas van a perder horas de luz, por lo tanto perderás productividad. Si en tu país es otoño o invierno la sacaría al exterior. Feliz navidad y prospero año

If you got the space to manage it, I'd remove the one not flowering and train out the other two to fill in the gap in your canopy. The one that's a photo needs some attention and switching to flower now isn't gonna help it, it might actually make it worse. You can keep photoperiods in veg indefinitely. I grow huge mother plants under cheap twenty five dollar LED shoplights in the corner of my basement lol. Get it healthy, prune it back if you need to, train it out more horizontal. Load it back in your tent when it's healthy again and your autos finish up.
