Help! Leaves curling in spirals

[Shandi]

I've been growing indoors and out, and haven't seen this before.
This is not leaf claw or cupping. It's actually curling in a tight spiral.

The strain is Pineapple Thai, and are showing flowers already.
Growing outdoors in greenhouse. Other strains not affected.

Has anyone seen this, or know what might be causing this?

I don't have pictures, so I hope someone knows what I mean.

Thanks so much,

Shandi

A few of mine did that after a neem spray.
I checked the ones with curl and they seemed to have a oil film that I washed off and they have come back almost perfectly.
I also got a good PH pen and moisture probe and let them go through a dry cycle so it could be any of the above.

it is caused from being out of ph....my guess to low....sometimes the ph can drop in soil if it is too wet also.....get a ph pen and don't overwater :jointsmile:

I had both PH and drainage issues so that must be it.

Thanks for your help. The plants weren't sprayed with neem, so it must be the ph, and
maybe overwatering.

Possibly a messed up light cycle. If the light isn't consistent and changes when it comes on and goes off it can cause leaves to spiral

Shandi please contact me if u still ever check into this post. I would like to ask u a few questions about the pineapple thai.

If you take a cutting from flowering plants then put them into a 24hr light cycle you will then get spirling leaves.

Check your ph, but don't rule out a nutrients issue either!! :smokin:

according to ed rosenthals' book that is a sign of a return from flowering to vegetative state.

however some of my plants that were under 18/6 lighting also did this when it got COLD in my area.. then went right back to normal veg.
