Jack is hanging in there. The fan leaves are yellowing and dying, probably a little early.
It's been a small plant and likely needs a lot more nutrients than I gave it in this Promix grow.
There's a good big bud on it so not a complete waste.
Looks like calcium to me. Possibly potassium but that usually wont show until flowering. Hard to tell with the current state. But week 4 shows the start of the issue a lot better
