Help Needed! Troubles with Fertilizers while Growing Zkittle

[Pacogollo]

 

HELP! Whats wrong with my Plant?

 

Hey, fellow growers!

I need your help! I'm having some issues with fertilizers while cultivating this incredible strain, and I have no clue what to do! I've been using Advanced Nutrients fertilizers as recommended, but something's not right. My plants are showing some strange symptoms, and I can't tell if it's nutrient overload or deficiency. I'm a bit lost here!

Here are some problems I've noticed:The leaves are turning yellow or brown.
Some leaves are curling or wilting.
Flower development seems stunted or abnormal.
Flower production is low, and the buds aren't forming properly.
