thanks guys, i'm not gonna quote everything but i really appreciate everyone's comments.
thanks soniq, you know i always enjoy a good chart. . . but i guess i should have quantified my pH problems. . .
just keep in mind changing out the res is a pain!!
so for the better part of a month my res would rise 1 or more pH points a day. . . the big problem with this is that I am only feeding them once a day. . . so although it would be great for them to see the entire range of pH between (on your chart) about 5.5 to 6.1, it was really only seeing one of those points per day.
when it came time to pH adjust, many times it would start out in the high 6's or low 7's. too high really. Then i would start adjusting it by adding some phosphoric acid (15%). even an ounce would barely drop it a tenth of a point. i ad mor and more and it slowly drops. when i would get it down to 5.8-5.9 it would get touchy. . . leave it for a day an it was back up in the 6's the next day or add more acid, which would drop it fast.
i went too far a few times, and by too far i mean mid to low 4's. each time, i said forget it because it would have taken 2-3 hours to redo iy from scratch, and by the next day it would be up into the mid 5's anyways. but i know feeding it this low did some damage to the fans.
after the long flush, i pH'd it to 5.4 last week tuesday, and today (saturday) my res sits at 5.7, i only topped it off and re-pH adjusted it once and barely had to do any pH'ing at all. i consider this nice slow drift to be stable, but it still moves a bit. jumping a point or more between feedings though, is obviously not very desirable.
i think obx is right when he says a lot of it was the drying out, but i think the pH def is a big factor too. . . i will work on getting some kind of technology to help solve this problem for next run. maybe an auto-doser of some sort.
PA, i think your right about the AN moving more than i'm used to, but also with the hard chem nutes, i should have known better and flushed it more often. like every week. lol. i don't use the bud blood or scorpion juice, but i do use a ton of the sensizym, and that's supposed to break down unused nutes into a plant digestible form. that's one of the reasons i thought i could get away with not flushing. i was wrong. FLUSH PEOPLE. FLUSH REGULARLY IN HYDRO!
AJ, thanks bro, even though i;m fu$%ing up the fan leaves lately in both the hydro and scrog, the buds are still perfect and jetting very tasty looking. . . just a little while longer. then, another mediocre success in the bag. lol.
