Blue Dream Auto? Photoperiod? ¯\_(ツ)_/¯

Hi @Chi_Town_White_Boy! Well I don't think you have a photoperiod if pistils appeared under 18/6 schedule. I think you have a monster, and you slowed it down each time you worked on it (topping, defoliation, LST). You must know that breeder's schedule are always optimistic, you can easily add 2 to 4 weeks in a non-perfect environment. Judging by the impressive growth since last week, I think she started to stretch, meaning that pre-flowering has begun. Patience is the key, keep up giving her good care and much love, you'll be rewarded soon with a monster full of flowers 😎 I'll be around, keep us up-to-date and happy growing 👊

I do think it’s a good idea. I have an auto I started at the beginning of April indoors. She never flipped to flower, so I put her outside in the middle of the summer. Once the daylight hours started getting less than 14 per day, she started flowering. She’s looking beautiful now. Hoping to harvest in 3-4 weeks now. You should be able to achieve similar results with a second tent. Good luck 👍

Hi @Chi_Town_White_Boy! I think you just named it: pH fluctuations, getting worst very quickly because of hot roots and maybe light stress (your new lighting setup could be involved). You can tuck the most affected leaves to increase light & air penetration (they won't recover) and double check that your pH-pen is calibrated, while trying to maintain decent temperatures in the air / in the solution. The spots should not spread as long as your pH is fine. Hope this will help, keep us up-to-date and happy growing 👊
