Defieciency or burn?

Lamp : 400 watts 2 feet from top
Circulation: fan outside of closest on during most of the day. At night closest is closed with no fan on.
Water: I let my tap water sit for a day then add some amonium sulfate to get the ph to about 6.5.
Soil :

Soil is rich organic soil with worm castings, bat guano, kelp meal, pearlite, chicken manure, dolomite lime. I got the soil from a garden place and added some extra worm castings.

4 parts soil from garndening place
1 part worm castings from gardening place.


Plants 4 weeks old


2 days ago i added 1/2 teaspoon epson salt/gallon and watered them because I thought it might be a magnesium problem.

About 2 weeks after planting, the lower leaves started turning yellow so i added worm castings to the top of the soil and worked it in with my thumbs.

Now in addition to the yellow leave there are purple spots around the edges and even some brown spots. I really need help
