ok i checked them out tonite and iv'e noticed on the lower bud sites the tips of the white hairs look a lil amber burnt color and the tips look singed could this be from maybe wind burn or nutes?? as i have a fan blowing on them. im in my 3rd week.

ph is at 5.5 ppms are 1500 res temp 70

p.s i forgot to add that this morning i went to check on them around noon and my a/c was off i guess i hit the button somehow last nite and the temp was 100 for about 4 hrs but i had a fan blowing the whole time but i saw no wilt or drooping all seemed good
