Yikes, 6.8-6.9 pH in coco? I’m surprised your plants are still alive honestly. I grow in coco loco and my pH stays 5.8-6.0. Not sure about the dry amendments as I use dyna grow. Maybe someone aill chime in who uses dry amendments. I’d get that pH down for starts.

Kinda way off. 5.6-6.2 or so. In early-mid flower I stay about 5.9-6ph.

And red petioles doesnt necessarily mean anything is wrong with the plant. Some strains do it naturally and some dont.

What if I'm using earthworm casting in my coco coir and organic dry amendments? I read thatbl because I have soil like components that I should find a ph between coco and soil like 6.1-6.5. Does that sound rite ?

When I do coco coir as a soil I keep it at 6.2
