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.

Should I cut the dried leaves at the bottom?Should I remove the dried leaf in the bottom? I was thinking that it might redirect unnecessary energy to the plant since the leaf might be too far gone to save. I was thinking of starting topping next week as well, when the fifth node start to show more.4y ago

Help plse. The small leaves on the buds have brown tips, some leaves are already completely .burned. Is this an nutrient-overload? I have flushed the plant now. Ph value is ok, Ec-value of drain is 0.6 ms/cm. Is this a problem for harvest? Guess it will be in 2-3 weeks. Thank youWeek 13

Nutrient deficiency or surplus?Hi Guys will post a pic shortly. Have to update the grow as we are actually heading into week 6. One of the white widows is a fair bit smaller than the other. And is showing some form of difficiency or nutrient burn. I think it may be due to to little phosphorus. Opinions?

Rapid yellowing of some leavesI've noticed strong yellowing of some leaves overnight. It usually happens to the lower leaves, but in my case the whole plant is pretty flat, so there's no real distinction between lower and upper leaves. Is that just flowers taking up nutes from lower leaves or some deficiency?

Browning of leaves on Northern Lights SeedlingLooking for some advice on the browning of the leaves and stunted growth of my NL seedling. It started occurring after a heavy water and appears to continue to creep. Thought it might be too intense lighting, so moved her. Thought it might be overwatering as well. Thoughts?
