Nice grow going on here. The entire Advaned Nutrient line...well, I'll be damned. And people have been telling me I have a lot of nutes, hah!
I can tell you guys have everything handled, but if you guys want any info to soak up and do what you want with, I can throw you a link to my grow because I'm growing with the entire arsenal of nutrients that a friend of mine, a 10 year + grower / hydroponic owner recommends and uses, having tested the products side-by-side. So far it's been amazing for me, and it'd definitely save you money in the future. And I / he uses coco as well.
Now, I know your guys' plants look really good right now anyhow, and it's interesting to watch the entire AN line at work, but yeah, I spent a lot of time talking to this guy about nutrients and how / when to use them and why, and I just want to kick the info to some others that can use it.
