Heat stessed, nutrient burn???

Ok I have 5 plants all of the same age, roughly 2 and 1/4 months old. They are still veg all in 5 gallon fabric pots and MG soil :wall:
( yeah I'm retarded!) , indoor in tent under viparspectra 1000w/230W actual light, half strength ff nutrient trio. So here's my problem, this plant has always been stressed by the heat but now it looks as if its dying/drying up browning. Is this because my soil is toxic with too much nutes from the MG soil?? I literally found a thread on this yesterday and it was the first time I heard of how toxic MG can be once you get into flowering or close to it. I've already flushed the plant pretty good last night just to be sure it wasn't to salty in the soil. Don't want to do it to the rest if I dont need to. What do you guys think the cause of this is? Should I preemptively flush the others as well to er on the side of caution, or just roll with them see how they dinish veg and flower?

Sorry for the pics did the best I could, always had shakey hands like an addict ina methadone clinic!!!
:shock::spew:

How close is light? Does it feel hot at canopy?
Temp humidity?

Just the person I want to talk to as well!!!!!!! Saw you help raspberrykiwi I think it was, that's how I became educated on Mg being so terrible as far as nutes!!

Light is 28 30 inches away
But it was about half that just moved it further away almost 2 days ago.
Humidity 50 to 65 avg loves to fluctuate
Temps get as high as 90F usually avg 81F
as I try not to run my ac constantly.
I think it may be the heat but I am just paranoid now of the MG soil lol.

If its only on top few leaves I'd say light burn/ heat stress
Doesnt appear to be all over plant just in a few areas.
Mg is fine long as you dont overfeed to soon ..its ok

That is the case too, bottom looks ok not like those top leaves. Also would you preemptively flush the remaining 5 plants in Mg soil, or just see how they play out and keep using FF nutes maybe more watered down??

I don't think it's the light distance..and temp may be a bit warm at times but I don't think is heat either. Recommended flowering distance for that light is 14-18". Heat stress would be more uniform, and the worst leaves aren't at the top. I can see some of those leaves dying and others above just starting to taco. Need more info but I wouldn't use any nutes right now.

Yes, your mg soil + nutes is likely toxic. Many have that exact issue with mg soil, preflower. Seems to do ok in veg, even flower for some - idk how. Flushing mg is not good, risking nute burn. I would transplant into better soil & and flip in 2 weeks unless height is an issue. What's ph? Did you take those pics under the light? Pic with natural light would be helpful.

So how long should this problem persist after flushing the MG. One of my plants is burning up the bottom leaves still. Should I flush again? Ran at least 15 gallons through it the first time. About a week and half ago give or take since flush just noticed problem persisting last night. I have also stopped feeding plant and going straight water now. What do you guys think I should do?

100% heat stress it’s all tell tale signs you can look up and it isn’t easily confused with a plethora of other diagnostics. If you can cool it down or your light if you’re not using an led
