pure blend pro bloom, cal mag, hydroplex

ok i have been using pure blend pro bloom and calmag once a week and my plants are looking great they are very healthy now i want to add hydroplex to my cocktail but on the back it says to use every time you water is this a good idea or should i just use once a week with my other nutes? i use 30ml per gal of bloom and 10ml per gal of calmag once a week the hydroplex says to use 2-5ml per gal every time you water

what nobody kknows i guess ill just use my best judgement and just add it in with my other nutes once a week

Every time you water means about 1/4 strength of normal fertilization.
