Run off PH is too high in Coco . You want the run off to be around 6.0 to 6.5 ideally . Could just be a slight lockout of phosphorus which is best absorbed around 6.2 .
Trying lowering your pH next few feeds to get it back down . Or feed more volume than you usually would until the run off pH lowers.

Burnt looking tips curled up are a sign of nutrition burn. Or your substrate ph is off. Was 5.8 going in or is it the run off ph. That is important as well. Should also have a minimum of a 20 percent run off each time. Plus growing in coco it needs additional cal mag. Coco absorbs it. Hope that helps and good luck 🌲🌲🌲👊

What is she telling me?Anyone know what she’s going through? Four weeks old, using tap water with hydroguard and GH FloraTrio nutrients. PH seems to go up from around 5.6 to 6.1 in a matter of hours. Ppm=635 EC=1.2 right now. Been going very easy on nutes, about half strength still. Could that be it?Leaves. Edges burnt

Surplus or deficiency?Can't tell if there's a surplus of nutrients or a shortage of potassium? One plant looks like nitrogen burn and the other two look like theyre maybe a little k deficient. Was thinking of chilling out on the feed on the burnt one and just feeding micro to the other two. Thoughts?9 months ago

CuppingOn the right plant in diary pic it shows slight upward cupping on the edges of a few leaves. There are a couple of others on the other side. But 95% of the leaves are fine. During my first try at LST I broke the main stem by 70%. I think this caused the cupping?Week 4
