Welcome to FC @Charbs32. It looks like a nutrient deficiency, possibly phosphorus.
Is this soil grown in a container or outdoor in the ground? If it's container grown then check the ph off your run off next time you water 💧
You need to adjust your ph down or up into the correct range to allow uptake and flush with 1/4-1/2 strength ferts at an appropriate ph to help bring things into line until you get run off that reads within range.
What ferts have you been using so far?
