These are lip smacker by exotic genetix.
About 5 days into 12/12.
Coco in 1 gal pots (transplanted 2 weeks ago)
850ppm gH trio and calmag feeding everyday
5.6-6.2 pH
55% rH 75-82 degrees


So I was feeding until I flipped to 12/12

.5tsp (2.4mL) calmag
.5tsp (2.4mL) grow
.5tsp (2.4mL) micro
.25 tsp (1.2mL) bloom

Since flipping I went to modified lucas formula:

6mL micro
9mL bloom
5mL calmag

Problem on the upper leaves popped up over night, a few on the bottom browned a while ago but I wasn't too concerned.

Updated pictures a few days later. Still confused. So far I was advised to flush the coco because it was thought to be nute burn, but now im leaning toward something else since its only affected the females. All males were just pulled and were green as could be.

I think you have two issues, ph fluctuations causing the bronzing patches and a deficiency in K because of the burnt tips and edges. I’d lay off the calmag for a while

What is your runoff PPM? What type water you using tap or RO? If in tap you don’t need that much cal/mag. Are you feeding daily to runoff? I have found that coco works best feeding light every day with plenty of runoff. In my experience with it anyway. I know some say no need for runoff if feeding light but I found they do best with runoff. And you want you runoff ppm to be no higher than 300ppm from the input feeding and if it’s way higher you need to keep flushing it till it comes down. Take a look at coco for cannabis lots of good info

Drop the calmag to 2ml
 
I have not foliar sprayed anything.

Using distlled (RO) water, I have not tested runoff ppm only input.

Thanks all for the advice, I have a bunch to go on now.
