On day 43 for holy water (left) and day 37 Sunday driver (right). Been noticing the leaves pictured below for the last couple days and was wondering what it could be from? I did have a small pest problem but was treated with 1 part rubbing alcohol and 2 parts water don 3 days ago

This is burning from over feeding.
Or most likely damage from spraying your plants with napalm (rubbing alcohol).
DO NOT ever use alcohol to treat ANY problems with cannabis, it WILL do more harm than good.
There are plenty of products out there designed for treating plants properly.
AVOID ghetto science at all costs!
