Hi all
Trying to figure out what is causing the severe downward leaf curl.
Trauma seed
Outdoor
Rapid onset
MIlls A B nutrients at right levels
In 10 gallon Geopot, not over or under watered
Outdoors . Perfect temperatures and sunlight
Her sister outside growing perfectly and her sister indoor growing perfectly
Any ideas?
Ironically is still growing and new leaves are straightening after several days

Plants look nice, even tho the new growth is clawing inward.

Warm weather? U must be south mid-west.

Happy Holiday's
Wish u the best on ur outside grow.

Have you done something with nutes or watering lately? Assuming you’re growing outdoors? Though it doesn’t look like it, check under those curled leaves for critters. Do they eventually straighten out? If so I wouldn’t worry.

With those swirly tops I think you've just got a fast growing plant with the auxins running wild. To be safe, I would give it a look under magnification for signs of mites, but if it's rapid growth the curling is a secondary sign and the swirly tops is the first. You just want to inspect to eliminate the differential diagnosis.

You might notice tops not looking as green as older leaves a couple nodes down. This can also be normal when it's growing super fast... the chlorophyll can't keep up but it'll back fill later. I don't see any signs it's over or under fed. Looks good. Good job.

If it's the new growth curling. Calcium, but do check under them leaves like the above suggested.

I accidentally left off THE most important bit of information... about 3 weeks ago, given I have 2 other fine growing plants, I went extreme Schwazzing technique on this plant and for a couple of weeks the growth was slow and notmal at the tips and then BOOM.
And I mean extreme ... just left the growth tips
So Ninjadogma seems to have nailed it ... the growth is insane from all tips ... this is 3 weeks after being leafless ...and I mean leafless ... I literally left the tips only and weighed all the stems so they are basically horizontal or even below horizontal
I have grown a lot of plants over the years and I have never seen growth like this
