FOR EDUCATIONAL PURPOSES ONLY. Diagnosing cannabis plant problems – Part 7 of our Know Before You Grow Series. To read more check out the article that goes with this video. http://wp.me/p4xMWW-9L
Most nutrient deficiencies and overages in cannabis plants can be resolved by flushing the plant with PH balance water. Trace element replacement nutrients like CAL MAG will resolve most deficiencies. This video will help identify: Overwatering, underwatering, powder mold, nitrogen deficiency and toxicity, magnesium and potassium deficiency, worms and bugs, heat stress, and light burns.

    I’ve spent about a year watching every video I come across and just found this gem.

    THANKYOU!! 💙



  16. joe barnes on April 15, 2019 at 9:39 pm

    Help. I have two tents. Last week I noticed an ammonia smell in one tent within a week the plants had died.
    Yesterday I noticed the same smell in my second tent and the plants are not looking good, leaves browning and sagging. About 6th week of veg.
    So disheartening. ><>



  17. Harriet & Lee Horne on April 15, 2019 at 9:41 pm

    This is an awesome video yaw..



  18. Timothy Crawford on April 15, 2019 at 9:42 pm

    If you may have over watered and you still have nitrogen in your medium during flowering is flushing even an opinion? And I’m assuming flushing means watering trying to flush the nutrients out using the proper ph right?



  19. Rod Gray on April 15, 2019 at 9:43 pm

    thanks so much,,,,,,,happy harvest…..



  20. Visions of Me on April 15, 2019 at 9:43 pm

    I have a plant a plant and my leaves are turning down and the texture is starting to look slightly reptilian



  21. Barry Hoppins on April 15, 2019 at 9:44 pm

    How do you pH water? Everyone always uses pH as a verb, it drives me nuts lol



  22. Brian Nishimoto on April 15, 2019 at 9:44 pm

    That was very good on what you covered but leaves can also show you that you may have disease or virus problem or even an insect problem and mites being some of the hardest to rid of especially the spider mite which can destroy your plant before you before you even get to harvest it.



  23. DVFDrinkOrDie on April 15, 2019 at 9:44 pm

    You’re not making sense when you start talking about nitrogen. You said you made the plant N deficient then you turn around and say its "classic nitrogen toxic" and show us clawing on the same plant. well which is it, nitrogen deficient or nitrogen toxic? It can’t be both its the same plant. You’re high



  24. Yung Grip on April 15, 2019 at 9:47 pm

    Do u guys have an Instagram page?



  25. Sadhguru Jaggi Vasudev on April 15, 2019 at 9:48 pm

    Thank you



  26. Vaping Gaming on April 15, 2019 at 9:49 pm

    Best diagnosis video ever. It would be really helpful if you guys could add a "time" menu to the video description for each issue. Either way, I have the video saved for future reference. Thanks for purposely hurting your girls to help educate the rest of us! The best way to learn us to literally see it.



  27. pghdave420 on April 15, 2019 at 9:52 pm

    ive grown a good 8 times now but stopped until gets legal here .my last 2 grows i started using leds.my plants would get soooooo many tiny rust spots then eventually the fan leaf would just crust up.bud still turned out awesome but deff been crazy last 2 grows with rust spots.do most think it would be a cal or mag deficiency?and yes water was right ph



  28. josh major on April 15, 2019 at 9:53 pm

    Thank you for this!!!!! I’ve searched for answers and found nothing useful, this was not the case!!! You just saved my room Lol and gained a sub!! Thanks again!!



  29. recordingIce on April 15, 2019 at 9:54 pm

    Awesome video guys 😀 Informative and straight forward. Not too much good information on nutrition deficiency and overfeeding. I would really like a book that shows many pictures for the same problem, like 100 pictures of calcium deficiency, 100 of Nitrogen deficiency and so on, all the books I come across only show at most a couple of pictures of the different symptoms.
    Great job stressing the plants just to show educate people. Do you take pictures of the plants, It would be amazing if you were to share those, then I would be able to make a quick .pdf or something 😀



  30. BANISHED ONE on April 15, 2019 at 9:55 pm

    Is bottled water good to uae for plants?



  31. Ray Ingraham on April 15, 2019 at 9:55 pm

    You guys are great. You ruined alot of good cannabis for us



  32. Tom S on April 15, 2019 at 9:58 pm

    You know what… you guys made a great video! Eventhough its old is timeless. I actually seen the light! You guys have solved everything! Thanks for this video!



  33. IAmmm Moo on April 15, 2019 at 9:59 pm

    Thank you! for this helpful video, you guys seem rad! Peace love and good growth in life and with plants.



  34. writhe86 on April 15, 2019 at 10:01 pm

    From what it sounds and looks like, after freaking out when I woke up, is that I may have underwatered my baby. The stem is still sturdy and strong but the leaves are sagging a bit. Last night she was fine so I’m thinking i either underwatered or it’s the Ph. I’m going to wait a few more hours to do anything so I can see if the leaves change up again. Thank you guys for putting this out there!
    Edit: thanks to this video I was accurately able to diagnose my lady and now she’s better than ever! She’s been transplanted into her permanent home and is now thriving 😁🌱🌳😥😴 thanks again!!!



  35. Danny Lawther on April 15, 2019 at 10:02 pm

    Great advice & Thanks !! Just one question ??
    What strain are the plants your showing us ??

  36. BonerMaroner on April 15, 2019 at 10:03 pm

    Thank you both for all the hard work this video must of required. More helpful video on PH meters and fertilizers would give a one two punch to your really good video, Thanks again.



  37. jurgenpinkman on April 15, 2019 at 10:04 pm

  40. Adam Foster on April 15, 2019 at 10:10 pm

  41. CK'sGaming Channel on April 15, 2019 at 10:11 pm

    Part A usually has Nitrogen, and my plants flower just fine with Nitrogen in Flower. So….

  45. TheAcidBrn on April 15, 2019 at 10:14 pm

    Thanks for biting the bullet and inducing specific environments/deficiencies to showcase for everyone. Quality output. 🙌



  46. Playingwith3D on April 15, 2019 at 10:17 pm

    my leaves keep saying "smoke me smoke me, I’m already good, and there will be lots when I ripen" But there never is. lol
    Oh, and I have also ended up inheriting some pretty sad plants that i nursed back to health a few times, yet i can’t seem to take a clone to save my life. go figure.



  47. C Man on April 15, 2019 at 10:17 pm

    Question of the day. Did you guys make a chart I can use? Great video but a quick reference would be cool!



  48. Frick-N-Frack on April 15, 2019 at 10:19 pm

    Great job. This is a really great video. I over watered! Thanks…. Super cute couple BTW.
