anyone having problems with GH MaxiBloom?

[ovendoctor]

was having a blast with the hydroponics till I got some bad nutrients

the last 2 bags of GH MaxiBloom were defective and I am still waiting for an answer from my supplier

the mix comes out brown in color and it killed the three tomato plants I used it on [normally pink color]

the tomato plants were roama's ,they had 20 tomatoes and over 40 blooms per plant and were very well developed plants

the other plants are Amish paste and are doing very well[didn't use the bad nutrient on them]

all in deep water set up

any thoughts on this problem will be appreciated

Doc.
