Learn to Spot & Treat POTASSIUM Deficiency – Cannabis Plants

Learn to Spot & Treat POTASSIUM Deficiency – Cannabis Plants

Today on Lex’s World, my guide on identifying, diagnosing and fixing K-deficiency in your plants. Potassium issues are trickier to identify than other deficiencies I’ve done videos on!

  8. justin Densebuds on May 19, 2022 at 1:24 am

    Good job man. You know ur stuff! are you from Canada? I noticed a lot of Canadian’s wear dark glasses in their videos no matter where they are. Why is that?

    week 5, day 38 of flower, and my girls looked just like those with the tan spots, leaf tips curling up, mostly at the top. i just watered using just calmag 15 ml … 1 gallon, 2 plants … hope they recover



  11. carl webb on May 19, 2022 at 1:25 am

    This literally described almost to a T, exactly what is wrong with a couple of my girls in my garden and they were all at different stages and showing different signs but everything is pointing towards this! Im going to do a thorough flush today and back off the calmag a lot. I was taught to always use calmag every feeding until flush time, never had this problem but i would assume that is exactly whats happening. Thank so much Lex! Youre the best man!



  12. Die Slow on May 19, 2022 at 1:27 am

    Great video it’s about to be august and one of my veg plants start to show these signs. I’m freaking out because it’s one of my biggest plants. 😢



  17. Mr mycorrhiza on May 19, 2022 at 1:30 am

    Nice vid😷



  18. Gary Phisher on May 19, 2022 at 1:31 am

    London UK. I planted a seed in May – it grew without much input from me – just watering. After two months I thought it was a male. Nevermind, I kept watering but only occasionally – didn’t know what I’d do with a male.

    September comes – my plant starts to flower – look again – holy shit it’s a female – shit, shit, what do I do – I panic – put nutrients onto the potted plant – the drooping leaves perk up.

    Watch it grow every day – should I bring it inside at night – I have a fully darkened closet with enough space.
    What should I feed it – some of the leaves have gone yellow – about a third.
    I’ve bought a Jewellers looky glass.
    I’ve ordered Potassium something off ebay – and potash.

    I’m panicking – I would’ve learnt everything if I knew I had a female!

  37. jack 3.5mm on May 19, 2022 at 1:54 am

    Honestly every single grow i have some deficiency on flower, EVERY TIME, I’m sick of it, still don’t know whether it is potassium or nitrogen



  38. Maureen Figel on May 19, 2022 at 1:54 am

    Hi lex and anyone that can help me,
    I have been having the tips and of the leaves turning brown and then traveling up the edges of the leaves.In fox farm ocean forest with no nutrients added until four weeks. When I turn the clock back this problem shows up shortly there after. Tried potassium supplement that did nothing. PH is between 6 and 6.5 for nutrients and the same for the soil. These plants are grown indoors under LED lighting. I am at a loss !!! Can anyone help me? By the way all my indoor crops are seedlings.

  46. R MOODS on May 19, 2022 at 2:03 am

    Finally got my answer thank you better late then never.



  47. Mr. Sour's 420 growing adventures on May 19, 2022 at 2:04 am

    I have had potassium deficiency in vegging. In long vegging potassium deficiency is very possible. Brown straight tips is potassium deficiency. It’s a ok video but some of the information is not accurate. Potassium is number 1 nutrition a plant needs overall



  48. The_Dude_Grows on May 19, 2022 at 2:04 am

    whole lot of info to say ph is out



  49. VM A on May 19, 2022 at 2:08 am

    I’m having a really difficult time trying to figure why plant is not 100% healthy. It’s close, but something is off. I use general hydroponics trio but cant find a good balance for this specific strain. Will pay for help if anyone wants to zoom with me and help me figure this out. Please reach out.



  50. burnett freinh on May 19, 2022 at 2:09 am

    bro i love you. everything explained in a simple well put together 5 minute video. i applaud you sir. 4 years later still the best potassium video on YouTube
