Leaves. Edges burnt

hey there you have magnesium deficiency you can tell from how the leaves are losing color , especially the bottom leaves. What you want to do is make a foliar spray with 1 ml of cal mag and spray on the leaves every few days for a week, the problem should stop spreading and the plants should make a complete recovery. Add Rhiz to the spray once a week for a bonus boost to growth. hope this helps ! :rocket:

Hey there, so first i thought about calcium deficiency because of the color and where it's located(where light is hitting that leaf) and phosphorus deficiency can do odd things like this also, but your nutrient line up looks pretty solid. Perhaps raise your ph just a couple points? Maybe that might be locking a few things out. Unfortunately with nutrients they're all available best at different ph's like calcium is best between 6.5-9, and phosphorus is between 6-7. So even though coco is best at a lower ph you may still want to aim above the 6.3 range and hopefully that'll make everything available.
Odd that its only affecting the one plant....but maybe the others are more resilient or other reasons.:v:
