The light stripping on leaves is light burn. The leaf rolling like a canoe, Light stress.
I'd say your light is to close buy a foot or more.
Tips burned. Salt build up in potting medium. She needs a good flush feeding.
What can you tell us about your lights?
What are you feeding her?
Are you sure she is an auto?
Wow, thanks! I should have asked earlier! I've a grown a couple plants, but I'm still a beginner.
I have now moved it from the lights. I do see crystals on the surface of the soil, so I think you may be right about the salt. I once had a problem with root rot, so I'm worried not to over-water. But it does look like I need to flush it out.
Until about two weeks ago, I'd been giving it a standard growth gel mixed with the water. The past few weeks I've been transitioning to
Atami Bloombastic. I'm using a Sunmaster Dual-Spectrum Lamp.
As for the seeds, I purchased a bunch of autos, Northern Lights and Purple Punch. I think these are NL. My other plants from this batch of seeds did autoflower. Alongside this plant, I have another one (I think it is Purple Punch) that looks healthier in terms of its leaves and it transitioned to flowering two weeks ago.
Thank you for this help! if you have further advice, I'm all ears.
