I don't like to give up until I have to... This is a new closet and I never tried to grow more than one plant before, so I'm still getting used to the extra work required, too. I have some ideas to avoid these problems next time around. At least my "backup plants", Tabitha & Libby, are still holding on. I see a little blue on top of the Perlite, though, so I'm watching out for root rot again. I'm flushing the Perlite & res with concentrated h2o2 added at about 5 ml/gallon. I'll spray the top of the Perlite with Neem oil tonight. Next time around I'm going to cover the Perlite with plastic more thoroughly when the plants are still small, to keep light out of it.
