Should I be worried about the tips of the leaves?

Hi. My name is Jungle, and I’m an idiot.

This is the THIRD time I’ve read the ml/liter and converted to ml/gallon wrong. The first two times, I underdosed CalMag. That’s not the end of the world, I suppose.

This time I overdosed (x3.8) ArmorSi. That explains why I’ve had trouble with my pH recently, and hopefully explains the plant behavior.

Changed nutes, carefully added the correct amounts of ArmorSi, CalMag, GH FL Micro/Gro/Bloom, and Hydroguard.

Hopefully it’ll be ok. Maybe what I saw was an oversupply of K?
