Major newb probs and q's ...HELP

First off I have two plants one is tall and spread ouut and the other is small and dense.

Second , one of them has a moarroon line on the top of some stems[can be seen in at least 1 picture]

Third, one of the plants has been developping yellow leaves.... only the fan leaves though

Finally, in the past couple days I have seen this bug, not sure what it is or whether i should care, very bright colors

did it get cold in the past few days?
the purpleing is from the cold

no, it's been just about the the same maybe a few degree's [around 5] colder, but these lines have been there for...at least a month, could it be related to a strain?

This is a pic of the yellow fan leaves that are worrying me...

Thats just N deficiency.Giveum bloom nutes.Kill that bug,they piss on your buds...

Thanks just real nervius (it being my first plant and all) i really just want it to come out good for my plants... what do you recomend to kill the bugs...something that won't end up tasting bad/being toxic when i smoke it
