Hi guys, I'm new been growing for a little bit but I can never seem to figure out problems with my plants , I try to change things with the information on the net but I'd figure I'd try here and see. The problem with my plants is that it looks like a nitrogen problem but they are showing signs off nute burn or is it a heat stress problem as my air con has busted. I'm feeding with a EC of 2.4-2.6 with organic nutes 2 times a day with a lot of run off , I know that It could be heat stress as room is 37c which is 98f but I just can't seem to get this right. I have attached pics of my plants. Any help would be appreciated. It's grown in a 2.4m×2.4m×2m Tent with 8inch exhaust and a 6inch intake for fresh air with 4 600w lamps in veg stage 2.5 weeks in grown in coco.

Welcome.I dont see any perlite in the coco so not sure how that effects watering times.EC and temp are really high,what is your RH ?Are you able to turn one light off?Do you have vented hoods?

Running that high of EC i dnt think you need to add anything.Your probably better to drop it down first same as temp and start there.

Ok cool , what's EC would be acceptable range 2.0- 2.2 or lower?

more like .5-1.4 or so. i don't grow in coco(i do dwc/hydro) but anything near 2 EC or over is usually way too high. My buddy grows in coco and uses Canna Coco nutes and gives like 4ml/gallon of a+b at the stage your at, with a max around 11ml/gal around transition/height of flower. idk what nutes you're using but yeah..

Also i know myke mentioned perlite but i didn't see a response, is there any in the pots? because that's usually a necessity.

Ah cool , I'll definitely dilute it for sure. No perlite , I tried it last grow but got less. So I went back to str8 coco.

Well you know your plants best,when did you up your ec?What was it when they were small?I normally run much lower at 1.1~1.5 ec.

I uped the EC probably too early after first week which is why they have nute burn. But I'll definitely lower it for sure. And thanks for the help I really appreciate it
 
If I were you...

You need to decrease your feed concentration; don't stop the twice a day feeding if you've been getting away with it.
You need to manage your pH...What are you running?
You don't need to worry about the perlite...it helps some achieve more feedings, per day, but it isn't necessary.
You need to manage your heat, by managing your lights...I would think, unless the sizes of your girls are deceiving, you can grow 4 solid plants using (2) of your lights (1200 watts). I'd cut back to (2) and in the process it will help manage your heat issue.

Good luck
