Hey Green, I have just seen your postings and thought id add my bit. I too seem to have this prob, when i do my morning inspection after 8/9 hours light everything looks like its on viagra but each day after about 13/15 hours things start to look droopy. Ive tried changing watering times to see if it makes a difference...it dosnt. the girls are very healthy and dont show any deficiency signs. i give them a light feed wen they need it. they are 5 weeks old now. I had the same thing on the previous grow and it seemed not to affect the outcome. im just resigned to looking at them in the morning now as i get too upset just before lights out. Are you still getting the same issues?
