I noticed that I had what I thought was nute burn, I had only been feeding half strength canna A/B coco feed so I was confused and just thought that I had a sensitive strain on my hands ( ph5.8
I noticed my lights were on 24hrs!
Would this cause the brown leaves?
Resolved
Week 4
Leaves. Edges burnt

Hello ! In coco not only the PH matter , the EC/ppm is very important as you need to check your EC to know how much nutrients you give them. Are you using canna A+B or just B (Your infos says only the B part) ? You need to know that the input ec and ph can be different from the output (water runoff) , so you also need to check the water runoff values and correct the input when necessary, for exemple you can have a 5.8ph input but a 5.5 output . That said , it's looks like a nutrient burnt to me. I hope it will help you :grin::+1:

Dude. In coco and hydro, an EC / PPM meter is a must, without it, you are growing blind.
Anyway, leaf tip and margins burnt, check; new leaves grow thin blades, check; it's a classic PK toxicity, go easy on the nutes.
