Does anyone use Fox Farm Hydro nutes???

Just wondering if anything is needed or suggested beyound the basic trio pack.....heard "cha ching" maybe worth it??

Also, should I imvest in the bushdoctor flush or is it a bunch of BS?

Does anyone even flush their plants every 3-4 weeks as listed on the Fox Farm schedule??

Thanks for the help!

Cheers

I've heard a couple guys here using Cha Ching, but personally have not.
