For those who read this thread earlier on, I am doing a Version 1 vs Version 2 experiment. The Version 2 did have an early lead. However Version 1 has actually surpassed Version 2. They started flowering, both about the same rate. But Version 1 poured on the veg Growth prior to preflowering and is probably going to be bigger by the end? They are not significantly different and both look great. Version 2 is stronger. My EC is 1.2 with version 2 and that is 1g less Calmag per 3 gal. My version 1 is 1.0 EC with 1g more CALMAG. I got minor top burn with version 2 @ that strength. But that tells me I am almost perfect. I may reduce the MC by just a little. I will try 13g per 3 gal, instead of 13.50. Aiming for 1.1EC instead of 1.2. I am upping my version 1 to 14g, because it is weaker.
