Got hydro halos setup because I need to be able to go away for work for a few nights, Was actually really easy to setup and works awesome, I got most the parts plus all my nutes from my local hydro store. I'm using cocoforcannabis.com as a guide for most of this grow and his site includes details on how to setup an auto watering system.
At this point I'm still using Professors Go Green for cal-mag and following the GP3 feed chart to mix nutes to the right ratio and then diluting with cal-mag water to target EC (300-400EC for wk 1).
Some of the plants had clawing leaves and were really dark green - I read that this could be caused by nitrogen toxicity and I'm concerned this may be due to the Go Green as it seems to be intended as more of a deficiency fix rather than a regular use cal-mag supplement for coco. Some of the leaves on one of the plants started getting rust spots like calcium deficiency, Canna Coco comes pre-buffered and I was adding Go Green so it had plenty, I think the likely case is that nitrogen toxicity may be blocking calcium intake also. I intend to change to Green Planets Pro-Cal which has low nitrogen and is made to work with their line of nutes.
Also we named the girls! My roommate and I were pretty baked if you can't tell...
