This is an autoflower in coco , using gh flora trio and calimagic , here what im giving them at week 7 ( 2,5ml micro , 1,25ml grow and 3ml bloom) and calmag at 2,5ml , this is for a gallon, water phd at 6,2 (600-700ppm) , run off 5,8 ppm 700. Is this overfeeding or lightburn ?? Its in a 2x4 groe tent using 2x 400w cob roleadro

Not overfeeding. I don't use coco but your pH seems a little high, I would drop it to 6.0, maybe some cocoa Growers could comment, good luck

I tried feeding at 5.7 and think have gotten worse in the last few days , run off was at 5.1 so I kept feeding at 6.3 and now runoff is back to 5.8-5.9

Imo. I would do 2ml Grow / 5ml Micro / 10ml Bloom
And 3-5ml CalMag.

PH'd to 6.8 and PPM to 600ish

I'm thinking Cal-Mag Deficiency. But also possibly Potassium Deficiency (which would make sense because your Blood feed is a little low imo.).

that is your issue speaking from experience my cheap one from amazon tested good at 7 and 4 but was misreading I got frustrated and bought an apera and found out that meter was keeping my ph above 6.5 but was reading 5.7 it was crazy because it test good at 7 and 4

This Stuff Right?

2-5-10 is Perfectly Fine. Just adjust your PPM before feed.

^BUT...... B.U.T...... that stuff is for Soil/Hydro.

I've not used it in Coco, but they have a special Coco nutrient Formula. Coco is known to hold onto and release certain nutrients later. This could be your problem.
