GH FloraKleen, Best Advice I'm Trying It Today

im doing a maintenance flushing today in my aero/nft tube system, i got a ton of salt build up on the walls of the tube and i just dont like it, plants are fine and24 days flowering, and the systems itself only being used for flower, label on this says 1-2 tsp per gallon for 1-2 hours, anyone have other recomendations for me?

cmon guys Mo' green needs a flava from you, i usually dont trust these lables cus they tend to make you use more than u should and wreck your plants so u can go buy more of thier shit, i have read somewhere that i should flush for like 24hours but then again that was for harvest

anyone? also i use a spray cycle of 15/30, since the lable states 1-2 hours should i keep the sprayers on for the whole duration or should i stay on schedule and let it run longer say 4hours?

so noone on this forum ever used Flora Kleen? hard to believe

Sorry man, i dont use the stuff, but i hope you get your answers.

1 ml per gallon works for me. 1 tsp. = 5 ml per gallon is way too much imho.
