God Bud- Canada legal grow

Over water, maybe over fert too. Lots of claw so def don't need to add any extra N nutes for sure. That PH is pretty low for soil so the color is probably just some missing phosphorus you're right there. You are already well into flower so I wouldn't worry about getting any leaves back. Those colors really came out pretty cool anyway. I mean if you're ever worried a good flush and then quarter strength balanced feed until the next watering is always a good start. But she doesn't look too unhealthy, just a little damp. Watch the temps, that can have a big effect on wet soil and locking up some phosphorus.
