Flip light schedule
Lovemabudstarted grow question 2 years ago
1 week into flowering and I need to change lighting schedule, complete reversal from night/day due to cold night tempswhen lights are on. Only way to achieve would be to have 24 hours of dark. There maybe an impact but warmer day temps I'm sure will benefit in the end. Thoughts

Unless it is an autoflower, absolutely do not do 24 hours of light with a photoperiod in flower phase... you will have a very high risk of causing a revege or some sort of repercussion for causing a major issue with the hormones inside the plant...
uninterrupted darkness is what causes / controls flower phase. do not fuck with the dark period of a photoperiod in bloom phase. no ifs, ands or buts and not a debate whatsover. based known science and knowledge that exists in the world...
One 12-hour light cycle lost is small potatoes, if necessary.

If its a must, I'd do it the opposite way round and leave the light on for 24hr.

Sorry hat the question earlier before but I'm new here so I dont know how to undo the solved quesion status. The LED has about 300W and I want to dimm it. not simply turn it on/off. Preferably with some kind of integration in home automation systems like Home Assistant. Thanks :)

When did the flowering start?The LED panel, after switching (Ts600 Mars Hydro), stayed slightly on even during the dark hours. I managed to fix the issue, but I'm not sure how to count the flowering period. The plant had shown some differentiation, a few pistils, and a bit of stretching. What do you think?

Too much light or PH imbalance?I dont know, something strange about the color, the spots on the leaves maybe? suggestions accepted. Maybe I need to add a fan ASAP, or let more air into the tent?
Dimmer is sset to 20% 25% , maybe I should give more light? or maybe less?
