One of the plants saw a decent bit of growth over the past week. Minor tip burn on it but I'm not too worried about that at the moment. The plant that was met with a bit of mold last week seems to be struggling a bit, not seeing nearly as much growth as the other plant. One leaf appears to be dying, the yellow burn is spreading further down the leaf, now starting to curl it up. The affected cotyledon also has blacked and curled up, I'm guessing it has died off completely by now.

My soil is two layers of Fox Farm soils, the bottom layer 2/3 being Ocean Forest and the top 1.3 being Happy Frog. I'm wondering If the tip burn may be from the roots reaching the Ocean Forest layer which will be a hotter soil medium.
