My recommendation:
Throughly flush the soil.
That resets us to square 1. After a flush we no longer have a nutrient overdose/imbalance problem.
THEN, after a day or so, start using a full-spectrum quality nutrient. Start with 2/3 recommended strength.
If you're in pre-ferted soil, do the same as above but re-start nute's @50% strength.
Note: certain lights distort colors, but if the leaves are a lime green as the pic indicates, your plants are starved for N (nitrogen). You want a dark lush green.
