Thanks for the advice! Obviously the simplest solution is that I'm overwatering. Since you say you had the same problem I'll try changing my watering habits.

I've considered the Nitrogen requirements in the future, so I plan to supplement the soil I transplant into with worm castings and just use the 6.6.6 liquid fert I have when the time comes. I also just planted another one and put a spoon of worm castings in the seedling soil as an experiment, so we'll see how that goes.

I'm growing Lowryder #2, so I need to maximize every moment on their fast track to flowering. I wish I had access to some superthrive or root hormone, but I don't.

Peace.
