Bought GS Kelp + Fish fertilizer, Will report how that works out.
A BIG CAUTIONARY WARNING: I suspect that the fertilizer releases some gas during transit. That had the jug under high pressure. I was obviously not aware of this and when I opened the jug, the gas exploded out of the seal and the lid hit my palm hard. (6 hours ago and the palm is still hurting)
I am not sure how to deal with it though
I am going to let the owners know about this flaw.
