Second Grow, Northern Lights Auto 2.0!

The plant grown under the $20 LED lights is huge. The two grown under the $60 T-5 are doing okay too, a little more stout, look good though. One is a little shorty, the other is pretty good size. No nutrients at this point, just fox farm soil, once they start showing flowering signs I will give them some Tiger Bloom to get em started. Some of the lower leaves have the same yellow spots as the last batch, I noticed this seems to happen as soon as I move them from indoors to outdoors permanently, I'm guessing it is something to do with the heat, or its possible water droplets magnifying the sun and burning the leaves, although I didn't water them in the sun. Not sure exactly what it is but it didn't seem to totally affect the plants before.
