Any ideas on what's going on with NL-2? Fan leaves are discoloring, interesting pattern. From Websites, I'm thinking a potassium problem, but am not sure. And am not sure how to correct this close to harvest (3 weeks give or take). Thoughts?

I think it is a magnesium issue, possibly some calcium as well. You are using a lot of P and K especially with The Open Sesame. The other nutrients contain high amounts of phosphorus and potassium as well. Potassium and calcium are two nutrients that can cause magnesium lock-out when added in excess. Excessive Potassium blocks the absorption of calcium, magnesium, zinc and iron. It is a game of ratio's that you must play and when you add 1 thing it effects another. Happy growing! đ

With a marijuana potassium deficiency, youâll generally see symptoms on older leaves, but not always. Sometimes youâll see the symptoms at the top of the plant. Leaves with a potassium deficiency get yellow, brown, or burnt edges and tips. The burnt edges may look a little like nutrient burn, except the affected leaves also start turning yellow in the margins. But if your this close to harvest I wouldn't worry. Try lowering your pH to 6.1 potassium is best absorbed at a lower pH.

I would say it's a cal mag issue, you're not providing any call mag on your nutrients and it s does provide some very important minerals not just calcium and magnesium. So you pain water every now and then. Might be worth flushing out and adding some call mag to your next feed.

Droopy leaves, curling at tips, and now brown/yellow splotches on leaves in DWC. Not sure what the issue isUnfortunately, I can only write so much here, but I have a lot more details in my grow diary. The droopiness started about 3-4 days ago, but now has started showing deficiencies in the leaves, and plants seem stunted on height. Day 19 since sprout.

Leaves have some spotsMy auto flower has started presenting some spots, it's on week 3. But I've seen these marks since the beginning of week 2, been measuring my ph and everything looks fine. Maybe the super soil is a bit too strong, and it has to get used to it? The lamp is 27 inches away.

Brown leaves - what am I doing wrong, folks?They look yellow in the photo, under 250W of blue light, but they are brown.
This starts at the tips of the large lower leaves and spreads quickly to the whole leaf.
Also modest edge curl.
What am I doing wrong here, folks?

Wilting leaves and copper spots? Save Me!These copper spots started appearing around 2021-01-28, and the wilting leaves started 2021-01-29. The newest additions to the environment were the much stronger MarsHydro 300w light. I've had to water more often because it dries out pretty quick with the rampant heat. what next?
