As the title says. Growing in soil 3 gal pots. This is an auto flowering plant. I honestly haven’t fed much just PhD water. The other plant I’m growing are thriving but I don’t know what to make of this.

are you giving her recommended dosage of bloom?

I agree with @Farnheit, it looks like your plant is hungry... specifically for potassium. It is time to start feeding every other time. PH adjust all fluids, even the plain water, to 6.3 pH.
