1 of 4 Plants Unhappy

Thank you Using a flowering formula - same blend on all 4 plants, only the Purple Power doesn't seem to like it

In coco only is your run off ph 6? You should be at 6.2, 6.3 ph in and coming out. I grow in coco. A cal mag is ideal as well 1ml to liter of nutrition. Are you keeping coco wet. It needs to stay 90 to 100 percent saturated. It is hydro growing in a bag. So lots of water in coco growing is required.

Too much nitrogen. You plant wants lots of potassium and phosphorus. Very little nitrogen after the stretch. The clawing is nitrogen toxicity, the spots are potassium deficiency and possibly phosphorus deficiency. Checking substrate ph is always a good first step before adjusting nutrition to ensure a good growing ph range.

Watering at EC 2.4 per guidelines Byron Bay Gold Flower A+B PH 6.0
