I dont know if you caught it, but that is your stem trying to grow roots in that picture, not a mold or fungus. I expect that this might be because you are overwatering or your water is not oxygenated enough, so the roots are not recieving the oxygen they need. This is causing the plant to try to obtain the oxygen elsewhere, so above the hydroton your stem is trying to grow roots to get more oxygen since it is not saturated up there. The bad part about that, is that your stem shouldn't be able to grow roots outside the bucket because it shouldn't be that moist and humid (which is needed for growing roots). I would would consider putting a piece of plastic over the hydroton and isolated the bottom of the plant from this moisture or you may run into mildew, etc.

On the whole, the plants look droopy, which in my experience with a bucket like that, is being overwatered or not enough oxygen from not enough bubbles OR to high of reservoir temperatures. Almost no one runs into the problem of water temps that are too cold. 68 degree water doesnt feel that cool on your hand. Honestly your hand is not a good indicator, as your water wont feel "cold" until its about 55 degrees and it wont feel warm until it is over 75 degrees. Thats a big ass spread in between. Your pH meter should have a temp on it. Whats the temp say for the water? Whats the pH at? A fluctuating pH can cause those rust color spots you have and also can cause your drooping leaves as the plant is not able to absorb the correct amount of nutrients and too high or too low of pH can lock things out.

sorry if that was repeated already.

PS. As far as the seeds, how can it happen? you started with seeds from a bag. That means the plant was probably pregnant with a hermie pollen (unless it was riddled with seeds, in which case its probably not from a hermie). If a female plant goes hermie, and releases pollen, it will impregnate your other females. However, since there is absolutely no male chromosomes, there is no way that the seeds produced from this plant love can be male. Ferminized seeds!!!!! Course, while that sounds wonderful, it means the hermaphrodite gene is going to be far more likely to show its head compared to normal male and female seeds. So while you know your going to get a female, you also have a good chance of a hermie. This is why people buy regular good seeds (not feminized) or clones. Even then, you still have a chance of going hermie if the plant is stressed enough. it seems very obviuos but your plant has been stressed plenty with the burning, overwatering, etc etc. This is more then enough to cause the plant to go hermie.

Good luck. If you want to continue the grow, try to remove the pollen sacks.
Racerx Reviewed by Racerx on . BOSS'S UNKNOWN WATERFARM GROW A short briefing: I started off with two unknown beans from a good batch I recieved. I planted the beans inside of the rockwool cubes, first. Afterwards, when the roots came out the bottom of the cubes, I then put them inside of the Waterfarm. I'm using a 400 MH and 400 HPS system for lighting. I vegetated for a short period, because of time (flowering limitations). I forgot to keep up with the dates of the pictures, so I have no information on the age of the plant at the time of the Rating: 5
