High humidity for long periods on root zone, causing lack of oxigen, water less in quantity or frecuency till you find the sweet spot.

Leaves hanging down
Northern Lights, Autoflower, 6th Grow Week. Some leaves hang down weakly since a few days, especially the upper ones. The weird thing is, that some leaves feel a bit dry, other ones feel normal. The other plant, Critical Auto, looks absolutely fine and healthy.

After the last watering, the upper leaves began to curl actively, what could be the reason? The fertilizers I gave were the same as last week. Ph was also good.

Persistent issues - wilted leaves, light-green splotches, brown roots
My plant has these issues. I've rinsed off the roots in case it was nutrient buildup on roots, which I still believe to be the case. I have given this plant a good amount of nutrients the week before. Does this appear to be a deficiency? Any ideas? Thanks all for responding

Sanity check on possible over-watering
I'm pretty sure this is over-watering, combined with some ScrOG training stress. But would of course love some input from some more experienced growers as well. Currently just letting her dry out a bit and then keeping more to a watering schedule.

Defficiency? 1st grow
I’m unsure of what is wrong with my plants. Leaves are turning yellowish colour and withering, first affecting old growth in week2F autoflower genetics. I use ph 6.4 water, runoff measured at 6.0.

Yellow/burned tips & curled leaves
I have an issue with some yellow/burned tips and curled leaves. I already suspect that mainly is from light stress but could also be a nutrient deficiency? I´ve raised the lights the max I can and keep it at 80% for 20 hours. Biobizz soil and nutrients. Thanks in advance!

Potassium deficiency?
Shes got about 2.5 weeks left, at first I thought the leaf discolouration was natural as harvest approaches but the necrosis has me worried. My guess is K deficiency. I was about to start flushing, will she make it to the finish line ok or should I attempt to fix this issue?

Purp stalks, weak leaves.
Hey guys i noticed that my stalks were all turning purple and my leaves are curling. Is this a nute lock out ? Or is it light burn ? I started them under a pretty powerful Led but still getting new growth through the last 2 days. They look thirsty but medium is still soaked.
