i don't need to defend rusty,nor am i trying to. what i think he's saying is no matter how good your harvests were, or that you think that were (not an insult) that they could have been better if you stick to one set of products. that's the way they are intended to work.

for example too much zinc or copper are toxic for your plant and can cause death of your ladies.

those are trace elements, so they are needed only in trace amounts. if two of the three or more of your products have these elements in them can you now start to see how this could possibly start to be harmful to your ladies.

you also fail to mention previous strains you grew then, or are growing now. keep in mind that different strains can have very different needs. (nutritional, light, what have you)
