a lot of times the only difference between soil and hydro nutes is that the hydro nutes contain ALL of the micronutes your plants won't get any from their medium, as soil plants will.

but like rusty said, contact the manufacturer. also, if you do use them make sure to flush at least once a month as they are very "salty".

headshake Reviewed by headshake on . Brown/Yellow problem i transplanted my soil recently and my plants might have been shocked a little. they were over watered at the time because my soil held too much water. anyways last time i watered them i added nutrients for the first time and i think i added too much. it said to do 1/4 of a teaspoon per gallon. and i used about an 1/8 of a tea spoon for a full cup of water. please let me know what you think the problem is i think its from too much nutrients although i gave my other plant the same amount Rating: 5
