Please look at the photos and maybe you can tell me what's going on. This happened in a big hurry! Worse since this morning when I watered them with PLAIN ph'd rain water, low ppm. I water every third day, have excellent drainage, am growing in organic soil that was/is a bit hot and caused problems early on (I don't add other nutes), but now they're changing for the worse as I write this. They are a month old. The leaf edges are turning light green with what looks like burn at the tips and some spots on some of the leaves
. This is my first indoor grow. Thanks for any input or questions you may have.
