Ok..ive read 10 days, ive read 2 weeks, been told every sunday cause thats when i smoke the least ammount of cheese, ive read weekly your suppose to change your res.. Again everyone's different and who can be the most efficent. but over all how often do you change your res? btw its a 12 plant ebb and flow with seperate buckets. I normally just every 10 days empty it out till its about 20% full then add room temp water back to the 20%, mix and then flood them with low strength nutes to help flush out (salt build up)?. then just fill to 50 gal. add calmag to get ppm to 150 because my well water is about 20-30 then micro gro bloom etc etc. basically what im asking now is i had eventually wanted to do 18 site but this was a first grow and a full strength hard hitting over ppm grow with expert GH series and then some so i wanted to see what grew the best and strongest with 5 feedings in day and 1 at night 18 hr lights 2 1000w mh and just all around a bad ass bitch to keep clones from. wanted some variety but looking for half cash to fund the grow and half medicine for a few family members with in our 10x10x8 room between og kush(royal queen) white widow(royal queen) blue thai(dinafem) critical(royal queen) pres kush pre 98 (royal queen seeds) and master kush (nirvana). so now that im down to the best eating and growing 12 from 18. how often should i change the 50 gal? when i top off or add water to keep the res at 50 gal, i add micro and grow to keep the ppm around 1200-1275. 2-3 week old plants. about to res change today. feel free to chime in on your process. heres some pics on what they look like at a little over 2 weeks. again this is my 1st grow im just a little skiddish i dont know as much as i think i do because i read contradicting results.
