yea my res is 20 gals and after the first ph adjustments it stays there for atleast 2 weeks i still keep a close eye on it though i noticed that the plant i have in the 5 gal buckets seems to do what ur saying i have to keep a closer eye on those.

and i noticed the wilt about 5 mins after i ph downed them but they seem to be doin alot better now i cliped the 3 fan leafs that got spots on them and wilted now there perking back up so i'll see tomarrow but i did change out the nutes with the ph'd water.


and as far as all the nutes i have i found a link to nute recipes and i picked the one from advanced nutes as thats what i had and the carbo load and f1 and silca i just added just incase i need them but i do like an 1/8th of those not full or half dose but i have noticed that i had'nt changed out my nuts in 3 weeks and they were still going strong so i don't know why people say to change every 2weeks as mine were still going good and still holding ph and ppm as stable as when i started so who knows
