@Rustynutz Welcome to AFN
Did you leave your nutz out in the rain
.
I am a hydro grower and have used Canna products with good success. I am currently running GreenLeaf Mega Crop 2 Part. Canna has a very good nutrient calculator on their site. If you request the light feed schedule and then start out at 50% strength it should be good for autos. I got up to about 70% before it started to be too much for the phenos I was growing. Your mileage may vary.
Since I am USA my brain thinks in PPM
I start seeds at 150 PPM and move to 300 PPM after the first set of true leave are about an inch long. The Mega Crop top is about 550 PPM for autos. I took my Photos up to ~1000 PPM.
