There are problems with the beginning of the explosion and leaves

Plant you planted at some point is stressed, we don't know why either. I doubt you checked pH at all. Most likely got a tds metre so who cares anyway. Is it even a photoperiod or automatic? It's all good buddy just add calmag. Maybe try and add some account activity,. Even a diary.

It’s very likely the problem comes from an incorrect watering routine. You’re giving too little water, too often, and too quickly. Lift the pot every day; when it feels light, water with about one-third to one-fifth of the pot’s volume. Then wait again until it feels light before watering next. Following a fixed schedule (like every few days) doesn’t work well. You’re watering too fast if a puddle forms on the surface or water drains from the bottom. If that happens, stop for a few minutes, then continue watering slowly. Lastly, please share more details about the fertilizer and soil you’re using. It’s unlikely to be too much light, as the plants would show clear signs of light stress on top. This is probably an issue related to watering or nutrients. Check the Dutch Passion deficiency guide for reference.

without knowing , i think they get to much light - try one day with ultra low light and switch then to 11.45h Light /12:15 Dark for a week and it should start flowering. and maybe to much Nutri, too. try less before anything else.

that plant is 95 days old?? If your growing a photoperiod plant it needs a light cycle change to initiate bloom. eg from 18/6 down to 12/12 If its an autoflower and not blooming you could try a light change to 12/12, but it might just be the genetics of the plant. Topping them or using LST can help control the height of the plant. Plants will not bloom till they are sexually mature regardless of the "photoperiod", aka the light cycle. Next time start a diary so we can have a better idea of whats happeing.
