I personally leave them in the dark for a day after they break ground. But it's safe to run the light at the schedule of your choosing. 🤘😤

Damaged Leaf - Problem Identification
I know it's probably nothing to worry about since this is my by far best growing plant right now, but it doesn't really look like a mutation, more like damage or something. This is the only leaf i encountered, just wanted to check if anybody knopws what it is, hopefully no pest.

leaves feel dry
What causes leaves to feel dry to the touch and curl down? These leaves are in the lower branches. Misting these lower leaves each day with water seems to help.I have been careful to not over water. Is it a problem with nutrients or humidity?

One of my 3 plants is significantly smaller than the other 2. Her leaves are multiple colours. She was late to shed her shell so I peeled it off myself. She is still steadily growing however I have been unable to diagnose her. The photos of her are labelled "sick one"

Name that pest
I check my plants multiple times a day every day. I found this spot and I'm hoping someone can identify the type of pest. I treated pillars with BT a few days ago. This was not here last night. It had also been raining of that helps. Thanks in advance.

Thinning out fan leaves?
I’m in week 4 of flower. Should I thin out fan leaves as much as possible to create more airflow and light to flowers? Or should I leave them on to retain water? Thank you.

Persistent issues - wilted leaves, light-green splotches, brown roots
My plant has these issues. I've rinsed off the roots in case it was nutrient buildup on roots, which I still believe to be the case. I have given this plant a good amount of nutrients the week before. Does this appear to be a deficiency? Any ideas? Thanks all for responding
