Nutrient burn or deficiency? Can't tell the difference
Seeing brown spots AND yellow tips at the same time. Some leaves have burnt tips (nutrient burn?) but others are yellowing from the bottom (deficiency?). How can both happen at once? Running coco with Canna nutes at EC 1.6.

Environment is key here. What's your temp and humidity? Sometimes the symptom looks like a nutrient issue but it's actually environmental.

Looks like a classic case. Check your pH first — 90% of these issues trace back to pH being off. Even small deviations can lock out nutrients.

Post a picture if you can — hard to diagnose without seeing the actual damage pattern. But from your description, I'd guess pH-related lockout.
