Nice job! Im growing gcs gorilla glue as well. We look to be using the same light, nutes pretty much but i can see some drastic differences. And i dont know shit but i want to share for posterity and in the name of figuring out how to do this really good. So, i have 2 that look a little like yours and 1 that you could actually harvest today and have some great product if drying and curing is done right. I could never figure out that timer and i have bipolar so i never know when im going to wake up so i run my tsw 24/7 and when i wake up i spray the plants, shut off the light and let it all have a rest for 1-3 hours. You can have much faster results leaving lights on 24 hrs but i think its best for the equipment and the crop. so why is one of mine ready to harvest at 8 weeks? no one knows. autos are weird and can change on you overnight. Also, i keep humidity under 50% and temp at 75-80 max esp during flower. I did get a 3x3 tent for about 80 bucks on ebay and a vivo sun inline inline fan for around 42 i think but i have the 2 that look like yours moreso in a closet now with a same watt light. just thought i would separate them. If you think of anything different that seems to work, please let me know. oh also, every 2 weeks i sprinkle about 2 tablespoons of epson salts on the dirt and water it in. I just took another look and there are people harvesting this same strain at all different times. so only God knows. Sorry to intrude but this whole thing has been driving me nuts for 3 years and its starting to straighten out. Best of luck!
