Is this a potassium deficiency?
ZhugeTsukistarted grow question 5y ago
Is this a potassium deficiency, and if so, how do I fix it?
Ec was 10 as of a week ago, got it down to 1.7 last watering 5 days ago by flushing and fed with Jack's 20-10-20 peat-lite today at 1.3 ec, runoff was 2.2.
Ph is around 6.5.
Pretty sure the calcium issues are fixed.

From what I can tell is that's one of her lower fan leafs? I'm not seeing a sign on anything else really except that one leaf? I'd probably wait to do anything for a few days till she can show you what your recent changes have done. She's looking healthy I'm just guessing she's getting ready to self prune a leaf she no longer needs. Happy growing!

Theres two tips of separate leaves in the first photo that are yellow and the two tips on the left of the second photo are turning a darker color its just a bit hard to see. I had already cut off what I thought was all the tips that looked like this, so I think the problem is spreading but I have obviously left just about all the leaves on so there might be some credence to the self pruning idea.

Brown tips on older leafsWhat indicates the brown tip of a single lower leaf. Growth is also relatively slow. I see this on my 25 days old Hulkberry Auto. The plant sits in a greenhouse on my balcony. Night temperatures go down to 8-12°C. No fertilizer used.

Stickstoffüberschuss?Habe bei meiner Auto das Problem das sie kaum in die Höhe wächst, dazu die Flecken auf einem Blatt. Ich habe aber das Gefühl das die anderen Blätter auch zu dunkel sind? Vielleicht wächst sie wegen einem Stickstoffüberschuss nicht mehr?Sollte ich erstmal ohne Dünger gießen?

Lower leafs getting yellow tips and spotsI just noticed that the lower leafs are dying, while other leafs are getting yellowish spots. Is this some kind of nutrient deficiency? The leaf with the yellow spots is near the air intake.
They didn’t get any fertilizer except root juice since the soil is still somewhat fresh.
