Im growing 3 plants in soil since 1st september,, maui wowie, G13 armageddon & white widow using fem seeds. Their in biobizz all-mix soil and are now being fed bio-grow @ 1ml/1ltr. I plan on putting them under a 400w hps 12/12 on 1st october,, according to the biobizz feed schedule i then start using bio-bloom and top-max. do these all get mixed together or do they have to be given seperate ? when using the bio-grow it brings my water to 6.6ph.... does using these others lower ph much ? Thanks
