Anyone use the fox farms growing feeding schedule? (for nutes)

Wondering if anyone uses the fox farms feeding schedule. If so...what kind of results did you have?

I waited till the lowest leaves started yellowing before I added nutes (as I was told here) which was about 3 weeks

I just added nutes, but have noticed some yellowing/browning of some of the leaf tips...

fox farms said use 2 tablespoons of big bloom per every gallon of water...i used a 1/4 strength (1 teaspoon).

I'm thinking I just need to use some of my grow big.

Ya---you need to add grow big------First feed should be under 400ppm's at three weeks---------1/2 teaspoon GrowBig/1tablespoon BigBloom. next time plain water then feed again @600. If you germ seeds again feed at the end of week 2.

grow big 1/2 teaspoon after week 2 and full teaspoon on week 3... On week 3 When I used to grow I would also mix in mexican bat guano with the teaspoon of ff growbig!!

thanks guys
