I put on a topsoil of N-castings on my watering 3days ago and the advancement of the necrosis seems to have slowed/stopped, while the first round leaves have all dried and fallen off, but there are a few more developments.

I watered this morning with some distilled water with a 1/4 dose of FF Grow Big.

One of my plants with the worst of the problems is displaying early signs that I have over-watered it, even though I waited 3 days between the last watering. I turned the fans up and think i will let them dry out to the point of slight wilting to reduce the possibility that my problem might be because of root-rot

My plants seem to be growing a little slowly, with one of my plants barely growing for the past 3 days.

Likely culprit is root rot or possibly still N defeciency. I dont think its pH this early in the grow

Any Input?
