yeah both. Nitrogen excess can create potassium deficiency, bear in mind. Too much N will block usage of K

Leaf Curling and yellowing on three week old plant, how to stop this gettign worse?
I am getting leaf curling and yellowing on my 3-week-old Hulkberry plant. I suspect nutrient burn, even though I am using what was recommended by my local grow shop and also RQS's website. I have reverted to water only and raised the light higher. Anything else?

Yellowing leafs and dying tips
Hello ! In the last few days I founded that some leaf started to yellowing and burning on the tips . Maybe it's all due to the flowering stage but I'll be more calm with your answers that are always interesting and helpful even if the platform allows only one to be selected.

Yellowing leaves on bottom and middle
I am growing in organic soil and transplanted 3.5 weeks ago from .75 gallon pot to 2.5 gallon pot. I noticed some yellowing on some of the leaves, generally towards the bottom but a little in the middle. Is this a cause for concern or do some leaves natural die off?

Spots/decolouration on leaves: 1 sideplant (that I grow next to my growlamp) is getting a few spots....
So, I have 3 plants: - 1 centerplant that gets most of the light & 2 sideplants (left and right) who also catch a lot of the light, but not as much as the centerplant: the sides arent getting direct light, more reflective light. ?? The left plant is showing a few defects. Anyone?
