So this stuff is super awesome!! I did a ton of research on trying to find a safe all around fertilizer and stumbled upon this and I decided to try it and WOW!! I had some comfrey plants that were not doing well and I mixed some of this in my watering can and watered the plants and they are super green and healthy now! I use this on my corn crops and my cucumbers love this stuff! I have been using liquid kelp for over two months now and I have not had any issues. No plant burn at all. This is now a STAPLE in my organic gardening!!!
