Any help would be greatly appreciated. Growing DWC, week 3 veg, using GH nutes (light). Ph is 6, though I think my ppm/EC meter may be off as its reading temp off by 7 degrees. Water temp is 77. This prob has been the case from the get go with this one and can't figure it out.

Well.... That's definitely not a potato.
 
Have you used magnification to examine under the leaves? Yet? What is your starting EC and are you checking that daily?

By the way that temperature is root rot zone. What do the roots look like?
 
I haven't, however I check EC daily but am quite sure my meter is shit so I am not sure if that's where I am off. I have two other plants in the same room same temperature and are doing fabulous. What would I look for underneath the leaves?
 
Looking under leafs for russet mites, but since your other plants are ok and in the same space you probably don't have to worry about that. If the others start to look bad you're screwed.
 
Doesn't look like bug damage to me. Not mites, thripes, miners or caterpillars. I think you have a pH problem or you're feed is off as mentioned above. The easiest way out is just use the Lucas formula on it and call it a day. You won't learn much but it will solve your problems. That is unless it's a root problem.
