If you don't keep the soil aerated in that first few weeks by either use of MTS or poking the soil a couple of times a week-it can become anaerobic and this will kill the plants-usually you will see the stem start to turn black. With the proper lights to support growth-the roots of the stem plants can also help pull oxygen into the soil layer to prevent anaerobic problems.

couldnt it also be a nutrient deficiency? Ive read about other people having the same problems with their stem plants and upped their dosing of K and it solved the issue.

Unless you have the proper color temp light-the plants can't use the nutrients in the water.
