I was thinking the same thing. If I closely monitor ppm and ph it should work the same.? I think the main issue may be with PH. Im going to use it.If it doesnt say it on the bottle....Its not the hydro kind.
BUT....Ive used it before with no problem in veg.
Thats a 10-4 Roger. I don't even use a ppm meter, i just monitor the plants and feed them as long as they dont develop symptoms of nute bure. Just start off very low and work my way up as they tolerare. 1/2/tsp/gal is the exact ratio I was thinking of starting with. Ill give it a res change Saturday and hope all goes well. Thanks every one and BSI keep in touch we may have to swap notes soon,.When I used it I stayed on the safe side. I started with 1/2tsp/gal. I worked up to 1 1/4tsp by the end of veg.
Thats as much as my plants could stand. Yours may be able to handle more...or maybe less. Start off lightly with it.
