Good all around nutes, using the complete line right down to their Ph up and down. But it takes me about 2 1/2 hours to mix and Ph 5 gallons of water. Well, that includes the actual watering of the plants and checking their run off.
Only thing I would recommend adding to these nutes, is Mg and S supplements. Which is in Epsom Salt. And, Epsom salt does not have any salt in it at all. So it's safe for organic growing. I've been using 2 tsp per 1 gallon of water. Works wonders...
With the nutes, been feeding my photo's full strength with no burn... I did find out though if you mix the nutes in your water before it's Phed to 5.8-7.0, the nutes separate from the chelating. This is one reason it takes me so long to make up the nutes. Have to Ph it twice...
I also find out that the General Organics Cal/Mg works as a great Ph down.
