I've been using up old bottles of base nutrients (for a while now, I was gifted an assortment) and needed to up my K. All the hardware store had was 1-2-5 seaweed extract so I've been running that as about half my feed and it's been going well.
I honestly prefer organic. Im using dyna gro in coco on 5 of the 17. With organic i only have to water every few days. Once a week i use a knock off recharge product. There are plenty of dry amendments with everything you need. Just have to make sure to feed the microbes. Kelp, molasses, ect.. A product like recharge that has humic acids, micorrhrizae, kelp extract, molasses and beneficial microbes all together. I like Dr. Earth, it has everything except molasses and magnesium. It's between $20-25 bucks for 5lb bag of veg and 5lb of bloom. Just top dress every 3 weeks. Make a tea with it if any deficiencies pop up for a quick fix. But my input is only 1 photo grow an a auto run. I want to get a 100 gal bed for my tent an do organic no till like Steve Cantwell.
Generally plants that have less light will stretch more to get too the light.
