The one on the right is a Greenpoint Doc Holliday, the majority of my grows have been Greenpoint and I have had excellent luck with them.
The plant on the left is a nerds genetics which I really know nothing about but I was gifted the seeds.
The left plant had considerable leaf tip burn so I gave it a custom hack job, I'm not expecting much to come from it but I will focus my energy on the Doc Holliday.
I did a flush to check the ppm's and 2000, yikes, lol, that's as high as my meter goes so who knows what it was actually. So I continued the flush until I got it down to a couple hundred and then made up some fresh nutes.
I'm learning a lot from this little competition, trying to push the plants seems more detrimental then letting things flow on its own.
