We need much more info: What are you growing in? Soil (brand), coco? How often are you watering, are you letting the soil dry back (if in soil)?. Are you feeding anything? What is the PH of of the water/nutes you're putting in? Without more info this is a SWAG, they may be overwatered. Unless your water is really out of whack the chances of a Boron deficeincy in a bag soil is very small.

before adding anything make sure soil ph is between 6.0 - 7.0 by checking runoff water.
if ph is good then i would say it sounds like calmag deficiency.
check out this link that shows pix of all possible issues. https://www.growweedeasy.com/cannabis-symptoms-pictures

I bet overwater is right, I've been spritizng the leaves and we just had a lot of rain, and those 20 gallon pots hold a ton of water.
The soil is some combination of Promix Organic Garden and FoxFarms Ocean forest plus some miracle grow or something random I was feeling at the time but they all grew monster plants just fine last year and have been sitting out over the winter normalizing.
My water is testing a bit high on PH 7.2-7.5

You’re growing outdoors? so unless the temps are above 75 and not lower than 60, it could explain why they’re so small, they’ll grow better in warmer weather. Remember that the soil has been sitting out getting its nutrients flushed out all winter, so you should feed as soon as they recover.
