Great advice as well ChadAwesome advice from RoosterTheCog.
@Conn The NPK ratio is the Nitrogen - Phosphorus - Potassium ratios, which usually are displayed on the bottle like 3-5-5. The plants do look like they may be starting to get some deficiencies. I'm seeing lighter color on the new growth, which typically means it is an immobile nutrient. But I do also see some yellowing on the edges of the middle leaves which could be a lack of phosphorus. A lack of that would also include lighter green on the new growth.
You won't be able to correct a deficiency if the Ph of the soil has locked out those nutrients. As Rooster suggests, try and get an idea of what your input PH is, as well as your soil PH which can be done by doing a slurry test. Once that is in order, then you can go about correcting any deficiencies.
Can you maybe go over the slurry test for him
I have not done one in a while, I think I use to use a coffee filter to filter before testing but not 100% sure now. My mind is old but not yet Gray
