What is wrong with these plants?

Hey,

Currently on my first grow. I just watered yesterday with a General Hydroponics light nutrient feed and also spent the day before trimming the plants to give me a reverse Christmas tree shape. The trim was heavy. I would say 35% of the leafs were cut. One hour before lights turned on Today I sprayed with Liquid Karma. I also changed my schedule from 230am to 830am to 430am to 1030am. When I checked on the plant they did seem springy and healthy overall but I noticed some leafs had discoloration. Here are the pics

You can't change light cycle around like that, set at 18/6 and leave that alone.

I couldn't keep up with 230am to 830am. Switching to 430am to 1030am is not that big of a deal. Some people Veggie with a 24/0 schedule and the plants thrive. But do you have any experience with plants being like in those photos I sent?
