Looks similar to nute burn to me. The ph sounds okay for soil. A little high if in hydro but still just about in the safe zone. keep using small amounts of the epsom salts and maybe use a weaker nute for a while. Dont do to much at once though coz it makes it hard to find the original problem!. OH YEAH Greetings from a newbie to the board

Damn shame about overgrow.
peace
cloudsurfer Reviewed by cloudsurfer on . Any advice? Hey all. I've just started noticing some leaves curling upwards and brown blotches developing on one of my plants. It's mainly affecting the biggest plant but I can see small signs that it's moving to the others too. I'm at 38 days of flowering now and at first I assumed it was a magnesium deficiency but the red stems are starting to make me lean more towards potassium deficiency. Just to double check my PH I went and bought a aquarium PH test kit and it was dead on 6.2. Yesterday I watered Rating: 5
