It's my first time growing kush after growing autos,I've had to work away during the week quiet a bit and this misses was left to water and feed, I'm growin a afghan and a 8 ball..... She over feed them which caused some pretty bad nut burn but I couldn't go on to much to her as she didn't want me to grow while I was working away... She sed the timer has been a bit faulty and they where on for about 16 hours the other nite, this has now been sorted but I came home today to find the hairs have started to turn brown on them but the buds have not seemed to swell like I have seen with my autos in the past....is this due to the nut probs or light schedule fucking up??? I'm growin under 600w hps
