The Lucas GH 3 part formula

Just for your bank of information guys I run an eighty gallon resi that has held solid for 2 full weeks now. When I do my full strength add backs I add the water first and then add in the required nutes. I am not trying to be exact on my ppms. I try to get within 100 ppm of my target range at finish.
I then check my ph and it has been right where it needs to be every time.(5.8-6.2) I have been really pleased with how it is reacting. I am figuring it is due to having such a large resi.

Thanks again Bear

Good luck to you hound -Jay

Mine holds about 25 gals total or something.....2 different reses...Bear I do want to try some different things like this 3 part but I know me well enough to know that if I don't understand it I will screw it up without a doubt. I have heard so many good things about the 3 part formula and feel better about trying something more complicated if it will increase yield etc....just afraid to jump into something I'm not understanding....I did study the back of the bottle and sort of went back and forth....yeah I understand this....wait....no I don't.....you get the idea. Any help, info, visual aids etc would be very appreciated. Thanks!

I will see what I can do. Have to get the little bear cub off to school and all that fun stuff.
