We are using Super soil with worm castings and pearlite. Babies started out fine and now we are developing yellow leaves. We added small amounts of dolomite lime to bring up the soil pH (it was at 6.0 before the add). Water pH is 7.0. Using Miracle Grow Tomato feed (18-18-21) every other water.
400w MH, lights at 19/5, 4x4 room, 7 plants 6-8 weeks old. Temps ar 70-85 during day. Dropping to 60-65 at night. Humidity 40-45.

Whats going on!? Any ideas?
