Run off PH

Thanks for the help all. Got a little calmag in the reservoir now, I'll lower the pH and try flush through on my next feed.

Hey there I grow in coco and can help. Yeah you need to run lower ph water through till you get a low run off then let it sit 15 minutes and add nutrition for current conditions. Always have cal mag in nutrition. I provide nutrition every other morning. Then I just add 5.8 ph water that evening and twice next day. Just enough on those 3 times to keep coco saturated no run off. It needs to maintain a 90 to 100 percent saturation. For first nutrition it should be between day 10 to 14 and super light. I use a few drops per liter on my first feed with 1ml to liter of calmag. My green crack diary was grown in coco, perlite, and growstone for better drainage but same thing. Feel free to hit me up in pm if you need more assistance. Glad to help👍

Servus Mate, I agree with gmslave. Just want to add that this would be a normal situation, having a higher pH at run-off... When your plant feeds properly, EC drops and pH rises. But it’s quite a big gap to 7.5.. Good luck further on! Servus👍
