weeell if you think you over watered it then drrry it out! if it looks like its rotting under the soil - like if the soil is slimy and your plant looks like garbage transplant to moist - not dry, not soaking wet, but moist fluffy well draining soil and train under a light with a fan on it. you should know in a couple of days if the colour comes back and the fan strengthens the stem up. only as much wind as the stem can currently handle though, just to aid in strong stem cell recovery and to get the plant on its own roots. if it looks healthy after a few days, water until sparsely until its growing normally then feed as you can best judge.
hope some of that helps.
below is what a plant should look like with a light close to it and a constant light breeze - short, green, and bushy
ok so i lost 2 to root rot(one my fault) and i noticed a little color distortion on this ones roots. the soil it was in was not going to dry out before i lost her so i did an emergency transplant into fresh soil then back under the lights. her leaves are hanging bad and leaning at the top so i put in a stake and twistytied it up. shud i give it water or keep it in the dry soil and watch it? i realy dont wana loose another HELP!
working wonders but I would have only done a half oz (1 tbsp) at that age. I only started using 1/4 str and the ladies seem to love it!
