[S3280]

Hello Everyone,

I need some help with my veg plants. For some reason, the plants are growing in a way is creating some circular leaf's and unhealthy looking new growth. Not sure what's going on. I use canna as a base. Please see the pics and let me know your thoughts.

Hi S3280
Hard to tell for sure from pics but they look like they're pre-flowering.
What are they? How are you growing them?

I had a similar problem one time when I used ant poison around my plants. I had a mound of fire ants that made a home at the base of my plants during an outdoor grow and I used some ant poison granules and it caused my leaves to do the exact same thing as yours are doing. I ended up remedying the problem by flushing the plants with plenty of regular water. Once the leaves were better, I continued adding my nutrients as before. It took about a week of watering daily if I remember correctly for the leaves to straighten back out. However, curled leaves can be caused by a number of different issues. There is a good article about curling leaves and their various causes here on GWE's website. Hope this helps.
