Common Cannabis Seedling Problems & How to Fix Them

Common Cannabis Seedling Problems & How to Fix Them

—-Intended for the 18 & over—-

Sebastian Good talks about the most common Problems you can run into in the first weeks of the Life of your Cannabis Plants.

Problems with seedlings are common and can end up affecting them further into their life cycle so it’s vital you detect and fix them as soon as you can.

Yellowing or deformed leaves, burnt tips, or even slow growth are signs of cannabis seedling problems, even though your seedling may be able to recover, it may have a toll on the final size and yields of your cannabis plants.

It’s definitely not hard to detect when something’s wrong, but if you’re a new grower, first you should know what a healthy seedling looks like.

Marijuana seedlings are super fragile and sensitive so you should take good care of them, avoiding cannabis growing problems at this stage is vital because even though your baby plants may recover, the size and structure may be affected, which will end up affecting your harvest.

If you have tips you can share with fellow growers to help them take care of their baby plants, feel free to leave a comment in the comment section below!

    You’re the best guys



  3. Death Rager on May 16, 2022 at 4:22 pm

    ”pro” tip: only feed nutes after youve transplanted. thats when the true veg phase begins. disclaimer, im not a pro lol i only have 1 grow under my name. it was a success though only 3 plants, 1 month veg , topped all twice and after the recovery of 2nd topping i lst’ed them all. it was pretty good. also, this alleged pro was dumb enough to not hang the light closer to his seedlings causing 3 to start hangin sideways lol. oh well. edit i had 200 grams dry weed from those 3 plants. 1 was critical mass from mr nice and the other one was super lemon haze.

    1 dislike from BC seeds



  7. SnoozerIIVMMXIV on May 16, 2022 at 4:28 pm

    What’s the @Sebastian favourite strain?



  8. GreatWhiteSti on May 16, 2022 at 4:29 pm

    I feel like all the above is wrong with my little girl 🙁



  9. what.tf.is.this_shit on May 16, 2022 at 4:30 pm

    Why does my seedling have a second row of leaves that look the same as the first row and not like a month leaf like yours at 0:55



  10. Taurean Wilhold on May 16, 2022 at 4:31 pm

    what is the recommended ppfd or Par for Seedlings?



  11. Common Knowledge on May 16, 2022 at 4:34 pm

    I’ve found that if you’re having issues with maintaining humidity, the best thing to do is get a space heater and a mist maker. The heat from the heater will compliment the moisture in the air the steam/mist maker is creating.



  12. Billy Norton jr on May 16, 2022 at 4:35 pm

    I’m using fox farm soil and my plants are 16 days old and all are having a rough time



  13. Marc Stephenson on May 16, 2022 at 4:36 pm

    feel very let down by fast buds in all honesty have swayed from there line after recieving terrible unripe seeds which yep did nothing waste of cash whole 3 pack which isnt alot but pricipal.. yet dutch passion n barneys farm (same technique) germinated fine contacted u being the breeder of these seeds and sending poor packs out to banks to got shrugged off n told not your problem because was from a different bank which cant understand even me not being a breeder could tell they were duds from opening them so u must of knew when packing to originally send off..as say let down big time from a supposed renowned breeder like fastbuds..made another purchase since but only 1 seed of fast buds hit the basket out of 12 n thats only coz wanted the strain n didnt have it in any other gentetics



  14. oliver armstrong on May 16, 2022 at 4:36 pm

    I’ve got 2 strawberry banana second leaves are just popping out but other two are dropping and pale?? Any advice as the others in my room are all ok



  15. Canubis on May 16, 2022 at 4:37 pm

    👍😆✌ it’s 420 somewhere



  16. mindmaniak bloodyT on May 16, 2022 at 4:37 pm

    Cannabis cotyledon seedling tip burn?? Why is that 🤔 3 weeks in age



  17. Callum Whitcher on May 16, 2022 at 4:39 pm

    I let the soil go almost dry before adding water/nutrients, this always results in the plant making the most of what its getting, sending veg into overtime. 🌱🌿💐



  18. Carolyn Cannon on May 16, 2022 at 4:42 pm

    You can use the inside of my breast as a humidor to germinate the seeds



  19. Vanessa Turner on May 16, 2022 at 4:42 pm

    My only issue is with stretching thank you so much! I never thought of how unhealthy it was🙏🏾



  20. sparkykid 157 on May 16, 2022 at 4:44 pm

    My baby fell over now she a bit different form her friends but got her mostly straight again



  21. Flanders on May 16, 2022 at 4:45 pm

    My leafs turn brownish atm.. don’t think I’m overwatering. Maybe not enough. Not sure. If Leafs turn brownish, is it to late to save them? Or can I still make it work?



  22. The Wanderer on May 16, 2022 at 4:46 pm

    Too much light will also make your girls start to lean, trying to escape the light.



  23. JayJaySloth on May 16, 2022 at 4:48 pm

    My seedlings have dark green dots on the leafs



  24. Sterling French on May 16, 2022 at 4:49 pm

    do you put clay in the botton of the fabric pots as well?



  25. Robert Renfrow on May 16, 2022 at 4:50 pm

    What about a week old seedling with good color and a thick short stem that has started to curve downward? Any guesses on that? It’s quite puzzling.



  26. Obi Wan Cannabi on May 16, 2022 at 4:50 pm

    are you kidding? Auto flowers are like the scared little dog that growls and barks at everything coz its expecting the cold russian climate to murder it any second.. they flower at the first bit of stress, they hermie… i cant believe im disagreeing with things 9 seconds into a video 70-80% RH is a stupid idea for a seedling, you will need to keep the soil so moist or osmosis happens in reverse. might as well throw your seed in a bog or swamp I bet these guys mostly sell auto seeds, its where ll the cash is, 600 seeds from one plant thats like 12k profit if you can get em out fast enough.. and autos they gotta keep buying seed, devious.. encouraging them to kill them too, man thats some Apple installing jumping nets type of devious



  27. Common Knowledge on May 16, 2022 at 4:51 pm

    I’m not a new-new at growing, I have experience, but those plants ended up getting ruined. It’s been a few years since I tried again and now I’m taking care of 4 plants as of now. My biggest plant (ice cream) is almost 2 months and the leaves started twisting (no curling). I need to know what this means ?



  28. Wedge Antilles on May 16, 2022 at 4:52 pm

    Yeah… I over watered is what I did. Thanks for the informative vid! Sub’d!



  29. Nick James martins on May 16, 2022 at 4:53 pm

    What doest leaves pointing upwards towards the light mean?



  30. Theresa Fulton on May 16, 2022 at 4:53 pm

    What do I if my cat ate the beginning leaves not the root will it still grow?



  31. Derek Dingman on May 16, 2022 at 4:54 pm

    The issue I’m having is my seedling stretched right up, and I was so happy to see him grow, but then the top of him just fell over and now his stalk is withering. I don’t really know what to do being how this is only second attempt at seedlings.



  32. Jesus Christ on May 16, 2022 at 4:54 pm

    Would 1200 hps over 16 pots be too much for babys?



  33. Joey Oneill on May 16, 2022 at 4:55 pm

    Got 17 right now, some stretching more than others and 2 are even falling over and dying and I’m trying to understand why they aren’t all growing the same. Is it different levels of water?



  34. Mohammed Kaleb on May 16, 2022 at 4:57 pm

    Overwater can be remedied by a shot of hydrogen peroxide



  35. w3vy on May 16, 2022 at 4:59 pm

    nice vid



  36. YoshiNøScope on May 16, 2022 at 5:00 pm

    Using happy frog and the mimosa cakes are stretching day 8 I moved light from 42 -24 and turned down the intensity to 30 from 50 but they stretched 4 inches too high , I’m gunna put in some more soil and pray the stem puts some roots out , any tips/tricks?



  37. Jonathan Kravitz on May 16, 2022 at 5:01 pm

    My seeds have a tap root- I planted them in soil. Do I turn the led lights on or leave in darkness until they sprout? I am unclear- first timer?

    Thank you

    Jonathan



  38. MyGuy-N-K-Y on May 16, 2022 at 5:04 pm

    Wtf is that



  50. Jim Malone on May 16, 2022 at 5:20 pm

    got a question. Arizona is going going into its cooler fall season. what are your thoughts for an outdoor autoflower strain for my area. And thoughts about geowing as the days are getting shorter. never grown auto, or outdoors, but wondering what your thoughts are.
