You do not have a diary so we are guessing based on one photo. It could be a magnesium deficiency.

Deficiency?
My current grow is on its 5th week of flower and many lower leaves on each plant have begun to yellow then develop brown spots. I’ve did a little bit of research and I think it could be a nitrogen deficiency. Any help is appreciated.

deficiency symptoms
I'm a beginner and some plants are getting fallen leaves. They are being watered with the amount of approximately 10% of the volume of the pot and an average pH of 6.5. Runtz has Mag deficiency symptoms after I fertilized, is she also lacking N deficiency?

Dried Leaves, Lockout or Stress. Week 5 of Flower
Plants suddenly wilting & looking crispy like they're dry, but pots are HEAVY! Suspecting root suffocation/rot ("wet feet"). Hard soil crust might be blocking oxygen. Roots are drowning & can't drink. It just happened yesterday since they look dried. Temp is 25C and Air 50%

Yellowing and dropping of leaves
Does anyone have any ideas what could cause the yellow and dropping of leaves for the Royal Jack. All plants are treated the same. The growth is stagnating as a result.

As you can see, the first two plants look quite good while the last two leave something to be desired. The leaves on the back left are curling downward and
and yellowish at the tips (in places). What could be the reason? I ordered some epsom salt to try it out (sulphur). I grow in floragard proffesional growmix (grown in lightmix from biobizz) and have so far only “fertilized” with supervit, otherwise only pH-adjusted water. pls hlp

End of Cicle or High stress???
Good morning everyone! First, thanks for the replies to my last question. 2 of my 3 girls are doing much better, but sadly one is still very stressed. As a beginner, I’m not sure if it’s normal end-of-cycle or if she’s still suffering. Thanks, Jack

Over watering? Asked a similar question before but want to save this plant
This has gotta be overwatering, right? The soil + pots I'm using don't seem to drain very well. Started drooping like this when I added a humidifier at around 70% relative humidity. Maybe pushed it over the edge? Going to home depot. Perlite? Change out the soil? Better pots?
