What’s causing this leaf curl?

How do you measure run off mate? I’m going to do that now to see if that shows what is possibly wrong? Is it a case of flooding the pot and testing what comes out the bottom?

Yeah I use 3 gallon pots that sit in their own trays and pour 1/2 gallon through. I use one of those plastic nutrient syringes to pull out 30 or 40 ml of the runoff and put that in a cup and test the ph and ppm. Coco can get some crazy ph drift if its not kept wet, its not always a problem but its happened to me when I fed less than 2x a day.
Ok great, and I use water that has been adjusted to the correct ph?
Hi mate, I’ve just done what you have said and the average run off is around 900ppm. That is with plain ph’d water.
What ppm am I looking to achieve?
Cheers

PH was coming out at 6.7-6.9. Is this high for run off?

Yeah when I am running coco I want my ph runoff to be 5.7-6.2 but I know people who say the ph runoff doesn't matter, they claim it's only the ppm runoff. I'd recommend to feed the plant with regular strength nutrients and lower the ph to 5.5 or 5.6 for two days in a row then see what the runoff is reading

When coco dries it is very salty due to being high in potassium. You get crisper nute burned plants when let coco dry out. Here is a good guide to water and feed. It's a bit much to read but you will be glad you did!
