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 with some epsom salts mixed in water. Today I think I'll take the plants outside and flood the hell out of them with some water.

Anybody have any other ideas? A quick reply would be appreciated.

Thanks ahead of time and here are some pics. One pic is just to show the purple stem on one of the plants.

What type nutes have you been using? Also are these in soil?

Herbus

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.

Yes they are in soil and I am using "Earth Juice" fertz. They go in combination with one another. i.e. for growth you use one teaspoon of bloom and two teaspoons of grow and every month one teaspoon of catalyst. I have been suspecting the catalyst perhaps.

I am pushing the limits of these pots because I was not expecting the stretch that these plants showed after forcing. I've definately seen plants in smaller pots that were definately rootbound and didn't show signs like this, however.

I agree with not doing to much at once and since I flushed them with two gallons each of plain distilled water yesterday and then finished by flushing with one gallon of water with fertz I will wait a week and see what happens.

These are the fertz I am using and this is my first time with these fertz.

Welcome to the forums and yeah it REALLY sucks about overgrow. Makes me kind've paranoid to post at all.

IF any LEO happens to read this I just want you to know that there are probably 10 more kids being forced to make kiddie porn because you decided that going after some pot heads was more important. I hope you're proud. Fucking losers!!!!
