Seedlings aren't growing

I’ve been successfully growing autoflowers for a few years. Following the same procedures as always, my last three seedlings failed to grow after transplant. This one was transplanted from a jiffy pot on Dec. 2. It doesn’t die, but it doesn’t grow, either.

One seed was from a trusted supplier with previous successful grows, but it was old. The other two are new and from a new supplier. Dirt is regular organic potting soil, which hasn’t been an issue before.

Thoughts? The picture is not great, but the new leaves are green.

Soil looks wet, just be careful when watering babies, they don’t need much. Happy growing. :sunglasses:

So you mention 2 separate seed banks with the no goes. Is there anything that is consistent between the failed grows that could be the culprit? Maybe the particular bag of organic soil is causing an issue? Same bag with all 3 attempts?

Yes, the soil is the same for all three. Is there such a thing as bad dirt?

Idk exactly but you could have a batch that didn’t get thoroughly mixed or whatnot and maybe it’s got a hot spot or something. I’m spitballing trying to find what factor they all shared that could’ve contributed to the 3 failed attempts.

Can you test the container for their current ppm and ph?

I don’t have a tester for PPM, but the ph is 7. I water it with tap water that has been sitting in an uncovered container for a couple of days. I am careful not to over-water, but yesterday I did give it a small drink of properly diluted Big Bloom, just to see if fertilizer would help.

7 is high and out of range for soil. Target 6.5 I’d say but you’ve been growing successfully for years prior to this right with all the same parameters?

I’d be interested is knowing the ppm’s (and ph) of the runoff after you ran your water through the container. It could tell us a lot about the soil anyways.

Yes, everything pretty much the same for years. It is a different brand of potting soil. I was using Happy Frog with good results. Now that I think about it, all my failures have been with this new bag, which is GreenAll natural & organic potting soil. I forgot to include an attempt with a clone outside using the same dirt. Never grew.

There’s at least a pattern we can look to then. Did your previous seeds pop and become seedlings and then get introduced to this bag?

I sprouted all of them in a jiffy pellet and transplanted to this dirt after about a week to 10 days.

I’d say your next step is grabbing a new bag of your previous successful soil and taking another stab at your seeds.(Happy Frog I mean. Sorry)

Yes, I agree. Thanks so much for your help! Do you think I could get away with transplanting this guy into the Happy Frog, or just cut my losses and start all over?

I don’t cull anything that wants to live and she’s clearly a fighter. I’d gently remove her from the soil and get her in some HF asap. She may need to be buried up to her 1st node for stability but no fear she’ll root out the same way tomato plants can root out of their stalk/trunk.

Transplant into happy frog. That should do it, but it might start flowering pretty soon if it’s already been alive awhile. I’d start over with fresh stuff if it was me. That soil looks rough.

What’s your temps and RH? Colder temps and low RH can stall seedling growth :love_you_gesture:

I wondered about that. At night, the house gets down to 58 or 60 degrees. But we’ve always kept it at this temp, and that hasn’t been a problem before. Not sure about the humidity, but we live in a dry climate.

Yeah that’s pretty cold for seedlings, I’ve had to keep the heating Mat on longer than usual lately :love_you_gesture:

Another suggestion would be fox farm light warrior starter soil. Great for seedlings. As for temps you definitely want mid 70’s for now, that does help.
