I have a few questions about the FF nutes. I have seen things on TV about how EDTA(the Disodium ethylenediamine tetra acetate rings a bell) has been proven to cause cancer. I looked at every FF bottles and evry one of them has it. Now do the plants convert all that stuff so ultimately we are safe? Im no botanist or horticulture expert so any info would be helpful. Please correct me if I'm wrong but this is how I interpreted the use of FF trio + open sesame... 2 weeks after sprout...use Grow Big First signs of bud, stop Grow Big and switch to Tiger Bloom and Big Bloom 2 weeks into flowering, add open sesame Stop open sesame 12-14 days before chop Stop TB and BB 7 days before chop so that plants can be flushed. Sound about right? Any help is greatly appreciated.
