I don't have a clue what the specks are, Tarev. I quit micromanaging my plants long, long ago. IF my plants appear healthy and I don't see evidence of horrible things about to happen, I just enjoy them even with all their flaws. If it is something easily controlled, like sunburned leaves, well, I immediately know what's wrong and can improve the growing conditions so that it doesn't worsen or happen again.
Plants are like people; there are very few "perfect" examples.
