Is this a potassium deficiency?
ZhugeTsukistarted grow question 4 years 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.

Help! Lower fan leaves drying out slowly at the tips and edges. Doesn't look like nitrogen deficiency to me, but please prove me wrong!10 days ago the lower set of leaves started drying out (they get brown not yellow). They don't receive light, but now it's already started showing on the third set of leaves. Does it look like nitrogen deficiency or can it be something else? Just gave it full strength nutes.

Wrong pH for three weeksI realized I was feeding my plant tap water with a pH of 8-8,5 for a good three weeks. I just flushed my autoflowers, three times the amount of soil with water corrected to 6-6.5. Will that solve this issue I was having (nutes lockout I think)? Did I fix my soil pH by doing this?

Leaves slowly dying. Nute burn? Heat Burn? Overwatering?Leaves are slowly dying on two of my plants. Starting to appear higher up at the tip. What could it be? PH, nute burn, too much light, overwatered? I may have overfed: 0,75mL Power Roots and Alga grow every two days since they were 10. Is it really bad?
