Bit of a mishap this week. Forgot to water one day so plants dried right out and my girlfriend cranked up the heat (I have a heat run going into my grow box to keep things warm because they are in the basement), anyways came home from work to open the door to have a peek to see the 3 droopiest plants I've ever seen (underwatered). I acted quickly and they bounced back within an hour but lower fan leaves got a bit of nutrient burn just from them laying on top of the soil. Lesson learned. Hopefully this is it for obstacles this grow.
