K deficiency?
PeterSagestarted grow question 2 years ago
in the last pictures you can see what to me look like an early deficiency of K. Since she is in the first stages of flowering I would say that's the case, reading the literature online i noticed a lot of similarities, what do you think?

Yes you correct. She is wanting a lot of potassium and phosphorus.
Might want to check what your soil ph is doing.

You're spot on.... and the fix is a bit complicated as you really need to figure out WHY you've got this deficiency... this is a good article to help you out... https://www.royalqueenseeds.com/blog-potassium-deficiency-in-cannabis-plants-a-how-to-guide-n671

What nutrient is causing this?I know for a fact that it is some kind of nutrient issue. I’m not sure what but that’s what makes the most sense. Because it ONLY shows on very early growth and then disappears as the new leaves continue to grow. I’ve been through very cold weather and never seen this.

Calcium deficiency or something else?What else can I do to fix the leaves drying out to crisps?
Started feeding with calmag 2 weeks ago just after flowering started but it seems to be getting worse not better in the slightest. Thanks in advance.

Unsure about waste of time without any nutrientsI keep seeing people say I NEED nutrients but I can’t get any. Is it not worth it without ANY nutrients? I can’t afford anything, not even calmag stuff. I’m thinking anything under 10grams, I’m just not going to bother let me know what you think.

Rust-colored margins and dots. I would like to go back to fertilizing but I am afraid that it is an excess of potassiumOutdoor in the vegetative phase, southern climate. Soil is Biobizz light mix. So far I have only fertilized 2 times with the tripack ph perfect Advanced Nutrients. These rust-colored burns are present on almost all older leaves. Enlighten me please 🙏

Hot weather, not enough super soil, Leaves Yellowing???????? Need Help. Am I losing these beauties?????HELP.. Temps in our tents got into high 90s, working on cooling. I thought we started to have nutrient depletion of the super soil as there is only about 2.5 to 3 gallons of sohum in each pot. Now I started feeding calmag, FF big bloom, FF Tiger Bloom. Leaves still yellowing????
