What's the ph of your rain water? Bad choice for watering cannabis, as it's likely too acidic.
You need something to provide aeration to the soil. (perlite)
What kind of soil, why no fertilizer or nutes?
Watering too much. Soil needs to dry-out a bit before the next watering. (root rot, nutrient lock-out)
What are the overnight temps?

Leaf mutation happens often in re-veg, clones and stressed plants. Normal leaf growth patterns return when/if stress is relieved.

:wtf: Looking closer before you post is usually a great idea. Yes, that's cannabis.
