Seeking Advice on Sudden Plant Health Decline

Ja da könntest du recht haben aber auch deine topfwahl ist mit Vorsicht zu genießen…. Sie trocknen sehr sehr schnell aus wenn sie nicht dicht an dicht stehen. Hatte schon ein paar versuchen mit denen. Wenn die Pflanze nicht zu stark geschockt ist schafft sie das aber noch gut hat halt einen etwas langsamer wuchs am Anfang.

Get some Bio Bizz ' light mix '. And bigger pots and water. Good luck .

They need water

Plants in pots that small will dry out in less than a day and show drooping leaves like this. Your plants need to be in containers 5-10 times larger than they are now. Temp fluctuations do not cause these symptoms. Water them well and they should recover..........but transplant them asap, that will be essential for their future health.

Es sieht so aus als hättest du sie etwas zu wenig gegossen. Die Temperatur Schwankungen sollten Indoor kein Problem weiteres sein. Du könntest sie auch bald umtopfen, der Stress von dem ganzen lässt sie etwas traurig aussehen. Aber sonst haben die beiden ein stabiles Wachstum.

It looks more like a ph thing to me,maybe forgot to ph down the last feeding?happens to me too a few times now over 5 years of growing 😂 you are growing indoors so the temps probably will not dropped under 12c at night so she will notice the drop in temps but not to the point it could cause that much of stress like your plant is showing, During the winter months here in Belgium,my day and night temps fluctuates between 26c and 14c in my grow space,when this happens i place my pots on a heat mat so I can keep my root zone at 20c at night this prevents them of slowing down in growth even if the air temp is only 14c during the nights Only when i flower in winter I need supplemental air heaters to keep the temperature fluctuations under control because this helps with the humidity in the grow tent,the bigger the temp fluctuates the bigger the difference in humidity with lights on or off,this could Jump from 45%rh lights on to 70% lights off and this is something you want to avoid in flower Happy growing 💪🏻✌️🌱

As long as your temps stay withing acceptable range your plants should eventually bounce back from the cold stress. If you don't see any improvement in the next few days I would wager your issue is your pot size. It looks about time for you to transplant them into bigger containers.

the soil looks pretty dry but yes a sudden drop in temp can be detrimental to the plants overall health
