Hey guys its my first post here, I just started my first grow and things are overall going pretty well. Ive done a lot of research but actually getting down and growing is a totally different thing. I was able to spot and notice nute burn in some of my plants, and have been only getting water for awhile now. The plants are still pretty young.

In this one particular plant I just noticed this white spot on it. It does not look like the nutrient burn I am familiar with. I am inclined to say its diseased and kill it before it spreads, but am not 100%. Is there anyway I can tell the difference between a diseased plant and one just burned via heat or nutes?
Pics are same plant

The second picture definitely looks like a nutrient issue but the first I am not sure. Any ideas?

And some of my healthy plants... :rastasmoke:
