Hi, I have attached some pictures of what my seelings have started to look like in the last day. I am concerned about the slow growth and also the small brown spots on some of the leaves. Here is all the info:

400W metal hailide light approx 3' above the plants
The seedlings are about 4 weeks old. They were transplanted to the hydro setup about 5 days ago.

The pH has been kept at a constant 5.2 or in that close range, but when I woke up this morning it was at 7.1

Water temp is about 68 degrees farenheit.
Water cycle is on for 15 minutes twice a day
Light is 24 hours
setup is a 2'x4' ebb and flow system


No nutrients are being used at this time since the seedlings are still young and the roots aren't quite developed. We added a tiny tiny bit of superthrive to the pH balanced water but it didn't really seem to do anything.
