Hey folks, I got some weird-looking leaves going on here, and wondering if anyone has seen this before or can identify it? This is a Purple Kush CBD 1:1 Auto in the following substrate:

3-gallon fabric pot
60% Fox Farm Ocean Forest
20% Perlite
20% Earth Worm Castings
6 tbs Dolomite Lime

Dropped the seed straight into the medium and simply watered it to germinate. This is day 18 since it popped, so needless to say it's moving slowly. Any opinions or advice would be greatly appreciated

Looks abit funky but should grow out of it, looks abit behind should takeoff around day 22 just establishing roots. How often you water and do you water to runoff

Since you planted directly into the soil with amendments it's probably just a little nute shock. Happens often when seedlings get into soil that's just a little "hot", it will straighten itself out as the plant grows some more.

Thanks, Phytoplankton. I think you're right - the pace of her growth has been increasing over the last day or two and everything else is looking good. Her stem is still a bit thin and needs support though...not sure what I did wrong there but I've got a little mound of dirt to prop her up and aimed more of a breeze on her to push her around so hopefully, that will do the trick.

Seedlings don't need so much nutes. And 6tblsp of lime in 3 gal is an awful lot. I would have transplanted into that after a few sets of leaves. Since it's an auto, I wouldn't be surprised if it started flowering soon due to the stress. GL

Why would stress cause an auto to flower sooner?

Yeah, I'm definitely changing my approach next time round and will let them pre-veg a couple of weeks in a peat pellet or something before dropping them into the bucket. I'm also worried it's going to start flowering before I have a chance to LST since the stem is still so flimsy.

Pretty common knowledge in autoflower community. The plant will flower whenever it wants to, if that means it believes conditions aren't ideal (stress) it will flower to try and preserve it's genetic lineage. Ruderalis is found in some pretty inhospitable regions, and it's adapted to survive. Those traits carry through.
Rootbound, overfed, underwatered, light cycle, poor temps etc etc all can lead to an auto flowering sooner than not having those stressors there. Keep it as ideal as possible and it'll grow closer to it's full potential before it flowers. Ever see a noob grow a thumb sized auto....? Yea....

I germinated three Strawberry Pie seeds about a month ago and two of them were in pretty bad shape. They had deformed leaves that were curled in some places and they also had pieces missing. It wasn't an issue of insects because the plants were germinated in a SuperSprouter in my house (I had to move them indoors because of the heat wave here in Southern California).

One seedling was so bad that I got rid of it but I kept the other two.

Per the pictures below, the one I kept is doing really well. It's smaller than the plant that was healthy as a seedling and the light level is about 100µmols lower but the leaves and stems are very well formed and healthy.

I'm just now starting my fourth grow so things like this are new to me but one thing that's becoming really clear is that cannabis is a tough sumbitch of a plant.

Absolutely zero reason to amend Fox Farm with excess lime. It is prebuffered - for weeks.

Viola …..
Addition of excess lime can make soil so alkaline that plants cannot take up nutrients even when these nutrients are present in the soil. The soil may also accumulate excess salts. These conditions stunt plants and cause yellowing of leaves. Often, while leaves turn yellow, the leaf veins remain green.

Yea I gots ya. I mean that’s the thought I had but it was just a thought. Good true non broscience info about autos is hard to come by. Yea was always curious how they got so petite lol
I did some autos my last run and did zero training to them and just let them grow out. Ended up with 5 oz per plant so I was ok with that :weed:
Wouldn’t say full potential tho bc I did light bleach the hell outta 2 of them lol. Was a shame bc the Trizzlers still tasted fruity af just looked like shit..

Captain Shit, thanks for this. Admittedly, the addition of dolomite lime was intended to provide calcium and magnesium slowly throughout the grow since I'm taking an organic top-dressing approach to amendments and not adding cal-mag to my feedings...so it was a bit of a gamble and it might very well be the source of stunting for this one.

I did my best to research what DL does for cannabis and how it can be useful so your quote is super interesting - can you provide me with the source? I'd love to read more about this as I'm always interested in counterpoints to my own information. Thanks!
