or at least hear growdrow's opinion on the subject...
i just changed everything out saturday and gave it all new nutes i even gave it lower doses there growing really fast i mean 2 to 4 inches a day roots and plant but all the leaves are curling up and i cant figure it out and it pissing me offi'm not sure man, but i can make some general suggestions...
make sure you completely change out ur rez/nute solution at the first sign of any problem. then bring it back up to the desired ppm with fresh nutes at the prescribed rates (but not necessarily at the proscribed quantities). plants can pull a particular micro or macro nute faster than the rest and then be deficient in that alone though the ppm's have hardly moved.
also, anytime leaves are healthy green enough (not pale) and they start to kink or curl or bend or twist then start looking at either over-fertilization or pH problems or nute lock out caused by poor water quality.
ya, that's reeaaaal helpful, right ?!
basically, make sure you are using RO water alone... then mix fresh as proscribed. make sure your pH is between 5.5 and 6.5 (might as well shoot for 6.0) ... and then make sure the ppm's aren't too high. personally i don't usually push them past 800 ppm, especially when having any signs of trouble.

what's ur initial water quality (beginning pH and ppm)? what are your pH and ppm at after adding nutes?.

and i've smoked dope recently... so you'll have to remind me of the exact media and brandname of the ferts you are using ..
the answer is in there somwhere... sometimes a particular brand of nutes will be genarally known to be a bit defficient in some nute or another...

it could also mean that you have 99 ppm of something like calcium carbonate in your water... this would cause the pH to rise (drift) even after you had it where you wanted it. if your pH stays in that range... 5.8-6.5 you wouldn't think it'd be much of a problem. and if it -were- calcium carbonate your pH would be higher than 7.0 to start with. is it well water? that is an unusual starting pH i beleive 'cuz cities jack the pH to inhibit growth of micro-nasties. 100 ppm isn't much, but that amount of a compound could, in itself, lock out a differnt nute that only occurs in small quantities in your fert mix.the start ppm and ph is 99ppm and 7.0ph
after adding nutes and ajusting ph its at 475 to 550ppm
an5.8 to 6.5ph and for some reason my ph always goes up after a few hours but the guy at my local hydro shop told me that was good for your ph to spike it meant that ur plants were feeding and taking in the good stuf
im sucking in really cool air from the a/c and i got my glass for my light and the fan sucks all the heat off of it.
aside from bubbling your water in a container for 12-24 hours... that fish tank de-chlorinator sounds like a good idea, especially if it also removes chloramine. if you find that to be working, then you'd know if the RO unit is a good idea (necessary) or not. but, ya, that water report could be informative. my water report was down-right scary.
just depends on where you live man... but in most municipalities i think a RO system would be in my top 3 for "Must Have Equipment".
Hey there, grodrowithme! How's it looking in there?? New pics?? You guys get any of your probs figured out??
I know the problems you have been having are out of my league.....I've been very fortunate with my water here, though DaGambler has me about convinced to go with the RO water; it may make my sh*t more stable pH wise.......
......and have a great weekend!
