First Auto run (I thought)

I have been feeding/watering with 1G per plant with my 5 gallon pots. I have discovered that's not enough and has been leading to nutrient build up. My run-off is over 3200 at this point. I'm gonna flush nice and begin to water with 1.5 g per feeding. They look better already, plant 4 was showing signs of a little lock out I believe but it is now under control. Plant 3 auto is about ready, plant 2 auto is probably 2 weeks away and I just performed my 1st flush. The wedding cake photos are gonna be big, I veged them for 6 weeks on 20/4 light cycle (on 10) for the last 2 weeks of veg thinkin they were autos, also minimal LST training and no toppin. Lookin forward to seeing how they turn out.
