Might be screwing up but I started this grow using the GH charts for medium growth. My pH and ec meters were not functioning properly. Plants seemed to do ok. They were getting too many nutrients. Purchased new meters and switched to the coco for cannabis chart. Plants not as dark green but seem OK. The gh chart had me adding calmag after the trio. Not using Si at the moment but did move calmag to the front-end. Trying to get into some sort of groove with the nutrients. Looking at the 1-2-3, 2-1-3 sort of ratio to make things a bit easier. I started converting oz to ml and using a digital scale. A pain but it did work. So , please, everyone call me out on the dumb shit. Lol. Still having fun.
Yeah, the GH feed charts show the nutrients in categories; the bottles give the order. For example, Armor Si they indicate to place it in first before any nutrients. On Calimagic, they indicate to place it in before the 3-part. The nute chart you have from CFC has the correct order for all parts and supplements - always stirring/mixing after adding each part before adding in the next one.
