I found this quote in Mister Source's thread, inside Cabinet Growing..

Tips burn and leaves curl do to high tds (total dissolved solids) of ions in the medium deposited by the nutes at a level the roots can not keep up in processing. Once they reach a certain level they become toxic to the plant and the plant will not absorb them as starving itself is healthier then uptaking poison. Yellowing of the leaves is usually caused by a low ph due to a high tds and soil that is to wet on the bottom of the pot. If oxygen can not penetrate the soil every 3 to 5 days the micro organisms which play a vital role in the uptake and breakdown of the nutes begin to sufficate. This is why it is best to keep so humid to damp. Ammonium nitrogen for example must be broken down by micro organisms found in the soil zone as well as rhizosphere converting it to nitrate before it is even usable to the plants.
This explains the situation that my plants were in, as they started to curl and lose the green freshness it had before.. What I did as a counter measure was cut off the bottoms of the cups and pushed into the center of the soil.. what it does is create an imploding archin the cup, and gravity will cause the water to pull down along the implode.. i put a screen under the cups to catch any falling soil.. the roots will hang between the screen holes (they're big enough, deginitely) and hold up on a nother screen bowl I have prepared (this way I wont over water, I'll be tending to the roots daily)

so yeah, i rearranged the bin, one of the plants stopped curling.. i just gotta wait it out, i'm also seeing tan/cream spots on the leaves-- does anyone kno wat this is caused by? I'm to assume its another symptom of the overwaterin.. I added more soil to the cups, covering up more of the stem, it should turn to become part of the root structure.. One of the seeds are comin out of the soil.. pretty much standing up, I see 2 leaves as well, but the seed's shell is still on the plant lol.. the other one still has to come up..
sheist Reviewed by sheist on . Back on Track Back on Track.. Of course we all heard the sad news that I had to kill my seedling, well I got 5 seeds cracked, 1 beginnin to sprout.. I got 5 styrofoam cups wit soil ready for them.. I'm gettin the supplies together tomorrow, officially, as i had them scattered from one friend's crib to another, i'll be officially constructing my stealth grow bin, just in time for these babies to hatch!
