first DWC attempt… failing horribly

This is my first attempt at DWC, i've only done one flouro soil grow before this, still very much a noob. This is a OG cush clone and I'm using fox farms nutes and ph up and down. So what has happened is I got the clone and started without a PPM or PH meter (*slap on wrist), then I got the PPM meter and messed up calibrating it… which resulted in over feeding it. I also believe it was under some insect attack, but I've been spraying it with 'don't bug me' which I think did the job. Also I think it has some light bleaching? not sure. I have no idea why the leaves are crumbling. Recently the leaves started yellowing too, could be from the nute burn, not sure. After getting the PPM and PH right, the plant seemed go gain some vigor, but the thing looks like shit. I could just go buy another clone and start over… but maybe I don't need to? Here is the progression of me fuckin up
