Slow flowering

So, if you think I'm wrong to point to a photoperiod that's too long in a case where the onset of flowering is late, please put forward your sourced arguments.

Some try to help as best they can. Some just bring their rage-filled faces and crappy arrachide-based jokes, just to cause trouble. Remember, there's a difference between debating and insulting. And unfortunately, the debate here is difficult because you have to systematically oppose inflated egos with deep-rooted obsolete and paranoid ideas.

The peanut gallery is at it again...."flush and reduce nutes so you can come back in two weeks so I can tell you you're underfeeding"....."reduce your light cycle even though it's not the cause of any problems"..... Most of the a-holes in the questions just dole out fortune cookie advice hoping to rack up likes or answers for one lame contest or another, actually helping you is more secondary and usually accidental lol. Aside from slow flower development, your plant looks pretty good. I'm tempted to chalk it up to genetics. Autos tend to be a little wonky and unpredictable. Ride it out, ignore the breeder's time frame recommendations and see how it develops.

Ich würde ihr etwas Klares wasser geben, sieht nicht so schlimm aus

Thats far from any heat stress, thats pure nitrogen toxicity, even leaf structure speaks about, not only physical look ( curl down ). I grew in heat, with limited air movement and extraction and still finished all plants well. Its coco, so overwatering is impossible. Flush her, review your feeding. You are damaging plant.

Hello my friend, this is clearly the symptom from heatstress. Next to that you are doing great! There are no signs from deficiencies or other issues. Keep the temperatures as low as possible. Switch the light to 18/6 and use the 6 dark hours during the hottest time of the day (between 11:00 and 17:00) to prevent heatstress and keep the climate stable.

Too much nitrogen/fertilizers can cause excessive leaf growth at the expense of flower growth. Go to a more plant friendly 18/6, give her a mild flush and reduce your nutes slightly.

I think she's fine. Heat stress will slow down the grow and with an auto this late in the game it can cause some developmental problems. The very last thing you want to do is stress her with overwatering. I would do a full flush and let her clear out and slowly add notes back in. Good luck!
