So, my plants have been attacked by some pest which I do not know what is, and some white markings in some leafs. Would like some help.

And also have two plants which I have questions about, one grew like with a double stem and other showed sex very early on, would like to know what is your guys opinion on that.
Thanks in advance.
Water schedule is when top inch is dry, so about every 2-3 days.
And fed nutes only once yet
