I don’t believe you’re supposed to let Coco fully dry. I think you need to drop the pH to 5.8 in Coco but I’m a soil person so I’ll let a Coco expert give you better advice.
I’m not real sure if applicable to your application, but my autos are 4 weeks old and getting almost a gallon every other day, and I’m already looking to increase.
I’m in straight coco. If you have perlite you may need more frequency… but you’ve kinda built a hybrid soil / media so not real sure.
I just tranplanted 2 GG#4 from solo cups 70/30 coco perlite to 1 gallon fabric pots. One of them also has the curled up edges on leaves. I think mine is transplant shock. How often you watering them, what kind of light you got HID, LED and how close is it to canopy? What’s your nute strength ppm/EC and ph?
The yellow edges became more pronounced. There are two or three leaves that are like that now so she’s definitely trying to tell me something. I’ll take another photo tonight when I get home.
Make sure you keep coco wet, it doesn’t like to dry out. Yiu cant treat coco like soil, you have to treat it like hydro. Make sure you keep your feeding schedule dialed and water atleast once a day.
Your running coco you want to water/feed daily with a PH around 5.8 as I understand things but I don’t run coco but many here do and that is their recommendations
