My second grow cookies

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.
