The only other variable I can come up with is root temperature. Warmer roots increase nutrient uptake compared to cooler roots. If the roots are warmer indoors this could account for the burn.
Day time temps.... nah not here in nor cal. Avg day time temp here is 88-93. Tent temp is 86 at the highest. Night time temps though are a bit different. Lights off at about 75 while at night here can go to 60 or so. This is all summer temps btw

If you will entertain me? I'd like to share a valid observation on the question.

When using LED's we start at too high a level. Almost always have to adjust. The sun is progressive and gradual. We subject our plants to stimulants multiple times than their size is capable of using. Inducing a normal condition in a more mature larger plant under the suns gentle touch.

Just a thought. Helped me since it hit me.

maybe the soil is to strong for those phenos and/or it's hot like ocean forest and it will balance with age
Well. Reading is fucking fundamental....

:wall:
I've used the red label outdoors this whole time. Blue label was used for right after solo cups for my outdoor plants.

I could have avoided alot of bullshit for myself if I had just read...

So im just gonna leave them in this red label now and let them grow into it.

Lights at 30 inches light was at 60% 100watt led

Burns all over but extremely slight.
Wiz, I have the same light and I have the same issue from time to time.

First, get the light UP to 36" above the canopy. Dimmer or not, at least 36" above the canopy. Let them grow into the light, believe me, that light has plenty of power.

These were never closer than 36" grown under my SF-2000:

Second, what is your humidity in the tent? Lately, I've been dealing with low humidity causing nute burn due to the colder weather. What I have found is humidity below 40% in the tent causes the plant to use more water from the roots to compensate for taking in less water thru the leaves, this causes an imbalance as the plant can't use the all the nutrients in the extra water being used to compensate for low humidity.

My issue primarily looks like a cal-mag deficiency, even though I am using cal-mag I still have the issue unless the humidity is above 40%. This has been happening since these seedlings sprouted back on 11/10/2020, right out of the dirt they were having issues until I got a humidifier and put it right in the tent. This is my first winter growing in this house, and my first winter growing in over 5 years, so I am just getting dialed in myself.

As for the soil, I only use Fox Farms so I have no comment on that except FF has done fine for me.

I just went to 36 inches. The humidity isn't an issue at all over here. Between 55-70 rh constantly. The issue is I used the wrong soil blend lol. It is what it is. They are going to go through some tough love before they are ok.
