So I'll bet they are still living and doing very well. Those spots seem like a "non issue" to me. Perhaps some water spots did that theoretical magnifying glass burnt spots thing? Can any growers with more experience opine? bump?

With those nutes I'd adhere to the Fox Farm schedule and I'm sure your half dose is a fine place to start. I'm not an "expert" although I feel safe saying that. Also here is a handy place for lots of info, this page shows pix of nute problems:
Marijuana Plants Problems - Yellow Leaves, brown spots, nutrient shortage etc.
I've read all their pages and would advise the same.
Enjoy!
