Nute Burn or Def?

Hello all!
One of my plants has shown signs that I think could be possibly nute burn or a deficiency, but I am not sure.
I grow in a 50/50 coco mix and temperatures hit 30 degree Celsius (Could this just be a nitrogen Deficiency with heat stress?)
What do you all think?

Plant looks very light in colour.

What’s your 50/50 coco mix?

Coco should be fed every time you water.

To me it looks hungry.

It's hard for anyone to give an appropriate answer to your question without a BIT more information.

A few other I can't think of

I'm of the belief that unless you got shit perfect 86 degrees is to hot.

With Coco you must ensure it has been rinsed, due to it containing residual salts (Depending on where it was brought, most hydroponic stores offer coco with this already done.).I will agree with jondamon, the plant does look hungry.Plants that are in the coco medium can be fed every watering (ensure that the medium is always saturated,with 10%-20% runoff.), as it replaces the nutrients in the medium and prevents salt build up that can cause nutrient burn. It is defiantly not heat stress, this is indicated by the leaves (There is no indication of heat stress presented in the pictures.).
Happy Growing

Ec : 1.2
PH: 5.8-6.0
Light: 250w HPS (50cm above)
Humidity: 50%

It may not be heat stress but I'm still of the belief that 86 degrees and 50% is to much of a spread. Sure some people can do it but not every enviroment is the same.

With 86 degrees you should be running around 75% humidity to have a correct VPD, look it up. By having such high tempa and low humidity your heavily increasing the transpiration of your leafs which is highly increasing the water and therefore nutrient uptake. With this increased uptake you are going to get nutrient burn or burnt tips.

If I was you I would either increase your humidity to atleast 65% to 70% or you could lower your temps to around 75.

With HID lights you don't normally need to run temps this high because of the IR of the HID lighting. These IR wavelengths actually increase LST, leaf surface temps, so higher room temps are a double wammy.

You, or anyone else, don't have to buy what I'm selling and I suggest you don't of anyones information. Instead take all this information and do some online research and find your own answers with all this data supplied.
