Seagreen sponsors the photo of the month here and i use it personally at 1/4tsp./gal. every other day and using my own tests, it has replaced all my other kelp,humic, and microbe products. I've looked at it under a microscope but it's so good i still fear they got something in there lol. I grow a lot of different ways but i'm trying tostay relevant to you, which i think is soillless indoor salts and additives. That way, i now use a simple "300mix" of 1/2tsp. Ksi(armorsi),flora micro, flora bloom each. I do 300mix one day, 1/4tsp.
Seagreen the other. In w5 i add dextrose(sugar) at 1/4tsp. on the
seagreen days. On my ig, most photos are grown with that. I change the ksi often with whatever i get free or cheap, same with the npk. I will be purchasing
seagreen when i run out though. All my growing and i haven't even used 32oz. up yet and i use it in veg also. Most even large plants will have very slight tip burn from this if you don't add some water days based on runoff ppm, color, and experience though.
Wanted to edit some quick stuff in. 300mix is usually 280ppm in ro, not actually 300. On the
seagreen days i water without runoff. Half your salts are unused. The idea is to chelate and use/break them down with microbes and humates from the
seagreen on the water days. When feeding salts i water with considerable runoff. Usually i water until it's pouring fully out the bottom with ease.
