Learn To Spot Nitrogen Deficiency In Cannabis

Learn To Spot Nitrogen Deficiency In Cannabis

Today I show you how to handle N-Deficiency in your sick plant. How to spot Nitrogen deficiency, how to treat it and how long it takes the Cannabis plants to recover. 2017 UPDATE RE: MOBILITY CHART…. The Mobile/immobile chart I used in this 2014 video is the exact one from the 2009 Grow Bible. When Cervantes published his 2015 Cannabis Encyclopedia, he changed it a little, but Nitrogen was still considered Mobile.

    Nicely done yery good!



  3. EREX NOVA on May 24, 2022 at 7:37 am

    I thought I had an N deficiency but there’s no way! I pH my water and I feed once a week. What I think it is is chlorine in the water. Watering with heavy water will show N deficiency like traits.

    Thank you. Straight to the point without all the extra talk. 👍

  6. Fredrik Sundin on May 24, 2022 at 7:39 am

    Outstanding! But do I continue with the nitro even after correcting the deficiency? One love bro



  7. schoolboy405 on May 24, 2022 at 7:40 am

    Hey Lex, is it possible for a pest to cause the same symptoms as a nitro deficiency?

    If you guys can’t be bothered to get fertiliser, add some coffee grounds to the soil. And water

    Im currently having this problem… 5 plants are not doing so well right now .. I was gonna transplant to 5 gallon pots to see if they bounce back .. this is my second harvest. My first harvest I didn’t have any problems at all. I guess nothing is perfect in life and you never from your mistakes. Any advice is helpful my leaves look dry…



  20. MrJustliketht on May 24, 2022 at 7:55 am

  21. olivier bilodeau on May 24, 2022 at 8:01 am

    hey the chart here says that chlorine is immobile and the chart in the phosphorus deficiency video says its mobile, same thing with zinc, it says mobile here but immobile on the chart of the phosphorus deficiency, wich one is true?

    Thanks so much!



  42. steve adams on May 24, 2022 at 8:22 am

    so what actually causes this,could it be that the nutrients are not good,ive had 2 crops that have had this problem using coco,the mother plants in soil and its fine ,same water being used at 6.0ph



  43. young E on May 24, 2022 at 8:23 am

    The only thing I hate bout lex is he doesn’t show us most of the problems in videos for sure he have alot to share with us but most people only learn and they see it in videos



  44. Roger Beaird on May 24, 2022 at 8:28 am

    thanks for the tips Baruch haShem ✡



  45. BODYROTTING on May 24, 2022 at 8:30 am

    How can I fix the second problem?



  46. Liqweed on May 24, 2022 at 8:31 am

    thanks



  47. Flat Out on May 24, 2022 at 8:32 am

    Temp can be a big issue as well ive heard. If above 73f believe it was the nitrogen and other needed nutes won’t be getting absorbed as needed. Could have plenty of nutes iron mag and nitro but if to warm it won’t drink any of it. Maling one think its nutes. When its just the temp. Correct?



  48. VM A on May 24, 2022 at 8:33 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.



  49. Nigel ten4 on May 24, 2022 at 8:35 am
