First Grow Purple Skunk Auto

Starting to look frosty! I reckon I stunted them a week or 2 early on when I tried to put both the veg and bloom lights on my LED for a day and they got real sad looking, so switched it off til they were about 5 weeks ish. I'm guessing harvest date will be another month away. I've added a pic of the roots on both my autos- they're creeping out of the bottom of the pots, don't know if this is good or bad but they seem to be doing good so far.
