You are right, 4L = 1G, roughly. I use Sensi Grow and Bloom also but I could only feed about half the suggested strength with my Autos. I believe they’re very concentrated nutes. So, 2ml per Litre or 8ml per Gallon max. If I went higher I was getting nitrogen toxicity and nute burn at the leaf tips.
