i'd say a good rule to stand by is veg 4 weeks from seed, then flower. the more you can veg the better though, maybe up to 8 weeks depending on your method of growing - you'll get more yield (assuming you have a strong light setup).
so it seems there is a lot of mold and gunk in the root system. The aerogarden sponges are covered in mold. I decided the only way these plants are going to live is if i get them in something else. So i've pulled them from the sponges trying to keep as many roots as I could. Pics are below...
the roots have actually be causing some problems... the largest root just fell off after week 1. The plant has grown since then and started new smaller roots which look a few thicker shorter roots now. The roots are brown but I've read that flora nutes stain the roots brown. Not sure if it is...
