Hey got a plant problem I'm looking for some help on- a couple days ago I started to get some yellow and brown discoloration on two of my plants near the middle and bottom. Over the past few days it's gotten serious- I have a few dead crispy leaves (mostly pointing up) on the problem plants and a few of the others are starting to show yellow speckles and some crispy leaf tips. I just recently transplanted them into foxfarm soil and lightly used foxfarms grow big and big bloom- it looks like maybe there is some nute burn going on? I'm using a 600 watt mh light, the temp in the room stays around 70, moisture around 40. I'm a total newb so any advice, including what I should do to remedy, is appreciated. Also, in case it's connected, all my plants have purple stems- so did the last batch (my first) and it didn't seem to be a problem. Thanx!
