The only brand I trust is from my hydroponic teacher more or less so I did learn Hydroponics from a video series……Harley Smith ,he owns KALIXor the NPK brand powdered kelp …..KALIX is the parent company.While I love seeing the success you have attained with the kelp, not sure I agree this is something that can be used on trees less salt-tolerant. Does kelp always contain sodium and iodine?
I use it on everything deciduous ,tiniest of seedlings….. totally fine With this specific brand…….. but ,yes I would be cautious of other brands.Good point
