I'm using 3g pots. I think the containers they come in recommend 3/gal for vegies but I've been doing a little less than 4/gal. 8 Tbs 4-4-4 and 3 tbs 2-8-4. I've been roughly following the Mr.Canucks youtube chan and how he does it. The PH I've been feeding is around 6.1 to 6.4. I amend the 3gal of coco with about 3 cups of worm castings and 30-40% perlite. I use Molasses about once a week in my watering's.
