Don't stop posting man, Everything looks great...
Your last few pics look like it might be time, but the scope is the only way to really tell.
How did they look with the scope?
How long is your 20# Co2 tank lasting you? I have a brain that measures PPM of the air and If I keep it slightly lower at 1100PPM, I can get almost 4 weeks out of a tank.
Your buds are killer lookin,
I am still trying to dial my new system in. All the bud has been good quality but i know I can get more out of them in terms of weight. Are those the only chemicals you are using right now? Thanks for the time you have put in already, it is inspirational.
P.S. I have much the same setup as you except I run three smaller trays in the same size tent (almost), to also run a perpetual garden, I can harvest every 3-4 weeks if I stay on top of it. Mine is all controlled with a master brain that is sick, so I know what you are talking about with it running it's self, just stay on top of the water and nutes and it runs good. Thanks again.......
