Do my plants look over watered?

My plants were doing great until about 10 days ago. I think I gave them a little to much water because they stopped growing. From the looks of the growing tips it looks over watered.

I bought a soil probe to see if there was too much moisture but it's saying almost dry. I tested the probe on other soil types and it showed wet after watering so I know it's working.

I even drilled extra holes in the tote to test different levels in the soil where the probe couldn't reach from the top.

I can't figure it out,I've went through the problem chart and I'm stuck?

Important notes: I have no way to weigh the tote but if I had to guess it weighs a little more than it did when I first filled it.. When this problem happened I accidentally gave it a 1/8-1/4 dose of AN big bud meant for my dwc. I also watered it again a few days ago very lightly due to the top of the soil being very dry.

The bottom leaves are turning yellow. I have a bad internet connection right now or I would upload more pictures.

It's an organic mix and it was doing great. No extra nutes except for the minute big bud mishap. They stopped growing about 10 days ago.
