How to fix yellowing

A customer has a question and I hope we can get some opinions on it, thanks

So my plants are yellowing @ the tip of the leaves on the bottom and a little bit on the top. I Know it’s most likely a nutrients lockout, but I do not know how to fix

Soil type and PH of your soil and water. Without that info you’re flying blind.

Nutrient lock out is due to a pH issue. It looks more like a toxicity issue to me, but that is also due to pH.

We really can’t be of much help without knowing what you have for pH. Under that lighting the soil looks overly moist. May just be my eyes messing with me.
