Autopot overwatering ?

Hello, i got 10 plants in autopots under a Lumatek Zeus 600w Pro. They all seem More or less fine exept one that looks strongly overwatered and shows deficiencies. Im using Mega Crop and a little bit of calmag with an ec of 1.1-1.2 and a Ph of 6.1-6.3. They are in a 50/50 Coco and Perlite mix with 1.5 inches clay at the bottom. Would it make sense to turn the System off for a Couple of days ? Or could it be something else then overwatering ? Temps are 25-30 Degree Celsius and 45-60% Rh. It looks worse in real life than on the pics.

were you able to resolve this issue?
Looks like to nutrient uptake is affected somehow. I had something similar to this happen of 1 out of 8 of my Gelato 78s.
the other 7 are fine... can't figure out what is wrong with this one... leaves just get worse and eventually turn purple and die.
 
Looks like it’s not up taking some of the nutrients. I set my ph at 5.8 but I do let it drift some. Hey sometimes you just have a plant that doesn’t want to act right. I flower 10 at the time but I’ll plant 13 just in case I get one like that. I got one now I’m fixing to pull.
