Started week 4 of flower. Saw these spots on leaves for 1st time today.

Wasn't sure if it's just normal as mature leaves get older? Checked on the leaves for bugs, didn't see anything?

Nothing to worry about. The plant looks healthy overall.

Thank you. I took off the leaves that are in the pics just in case but will know not to freak out in the future lol.

It's some type of minor deficiency.......not bugs.

Week 4 to 7 of flower and led lights are basically the most calcium and magnesium focused plant grow period. More than one journal I read showed this. I got one in week 5 from a missed dry cycle. Does not look the same as my damage but just keep an eye out. Spots at first and then leaf fade with necrosis starting at the tip is what to look for.
