Ah well, now I have a problem. I left the plants for 4 days again due to a tight schedule and suddenly they seem to have developed some deficiency. The buds are still shaping up nicely but her leaves are really suffering. I think it's a magnesium deficiency. The temperature outside dropped quite dramatically and since the room is not heated the temps in the grow box dropped by 7-8 degrees which probably didn't help. I'm buying a magnesium fertilizer asap and hope that I can save all newer leaves, since this plant doesn't have that many leaves anyways.
