Germination was successful and she was growing nor...

Did the top get too heavy for the stem to support? If the light is too far away or not strong enough, seedlings will stretch & eventually topple over due to gravity. But the problem could be anything really. What kind of soil are you using? Are you adding any fertilizer yet? The soil looks kinda wet & bogged down so it may be an overwatering issue. You definitely shouldn't be adding any nutes or fertilizer this early (assuming you did; your profile doesn't give much info). You can try propping her up on a stake of some sort but IDK if it's salvageable at this point honestly. If you have any more seeds, you might start them now just in case this one doesn't make it. Seedlings need to mostly be left alone. Light, water & good air circulation is really all they need at this stage. Good luck!

I think your soil is to wet not draining the roots maybe suffocating

Hey Jarad she looks like shes stretched towards light? How theyll get overly long. I see youve got the 150watt how close is it? Possibly build some soil up around her for support, it might seem like taking away growth but at least she can stand straight. If you can bring light closer do so. Hows your night temps? Any nutes yet? Lastly can you put a clear cup or similar on top to really boost the humidity, poke a hole or 2 for some oxygen and of coarse move it occasionally. The soils looking a tad dry also. Best of luck friend, i really hope she pulls through for you.

Hello @jarad ! Except from that white thing suppressing the seedling i can't really see anything wrong. Why did you put that thing? Although i can't see very well from your photos. . If the stem of the seedling got suddenly very thin, the seedling felt down and you put that white thing to support it then you have pythium. If that's the case there is no hope to survive. If you put that white thing to make LST then remove it because its way to soon for training. Happy growing ! 👊

Hi @jarad! Well we're missing a lot of crucial informations here, what's your medium? How did you germinate the seed and when did you transplant her into the container? Have you been checking the pH of your waterings? How often do you water and with how much water? From what I see on your pictures, I think that "heat + over-watering + wrong pH range" led to this situation. I'm not sure I'd try to save this girl, even if you manage to save it, she will take weeks to recover, and the yield might be severely affected. Try not to reproduce your mistakes with the next seed, we'll be here to help you out. Happy growing 👊

I have less Hope for your GIrl, Sometimes they just dont get it.....Try another one happy growing

hey man looks like you over watered at the wrong moment, i would maybe use precise watering and pray she survives, try using rhiz and rhiz spray to try to save the baby, but i guess she's gonna kick the bucket buddy... good luck !

Hello! I am sorry but she is dead or will be soon. I bet on an overwatering as your medium looks really wet. You should sprout another seed as soon as you can. Hope it will help you 👍😁
