What's wrong and what do I need to do to fix it ?

90% of the time it's a PH issue when plants look like this. Don't use tap, or even well water if you live in an area that gets its water from a limestone aquifer. If you live in the midwest you need a filtration system or RO. My water clocks in at between 7.7 PH which is 7x higher than 7. It's absolute and total garbage. When you add pH up you can smell the chemical reaction.

You've overdone the nutrient for sure, or your ph is far too low, or both.

Soil - plain water rinse, no ph adjustment if between ph 6.5 and 7.5. Wait for signs of improvement before giving any nutrient again.
The soil may have ample nutrient for now anyway.

Hydro - rinse with a very light nutrient solution, ph6. Then resume normal feeding schedule with lighter feeds.

Generally sativas are lighter feeders, just keep it in mind.

Touch and go, but the plants should turn around.

Best of luck!

7.5 is way too high. It's 10x to 50x the optimum amount depending on the strain.

You're lucky then. I've had trace mineral lockout quite a few times especially with Sativa dominant strains. Plus, my tap water smells like a swimming pool.

where im at you dont use the water from jan-march. its stronger then a swimming pool , HIGH amounts of chloramine in there along with all the other minerals.

Soil fluctuates , so between 6.2-7.5 is fine but there is no good way to test it so dont worry about trying to change it.
