Hey,spots are an indication of mites or thrips which i don't see...so i think ur in the clear with that........looks like nute burn,but more likely water burn from excess dew or condensation on your leaves,maybe ur foliar feeding...? Just be careful about getting excess water on ur leaves and look for and prevent any further problems with getting it on them....and ull be ok...later man.
