Plant's Fan Leaves Brown, Brittle, and Are Curling

About 2.5 weeks old. Growing in a bubbleponics. pH = 6. Idk if its the lights are too hot, or if its possibly nute burn.

pics were too large in size too upload to the site. any help's appreciated. one love.

This is the same thing happening to my plants. Growing bubbleponics as well. I m currently in the middle of week three but cant figure out whats going on.
I feel like its ph lockout but dont quote me on that lol. hope someone replies with help soon

kinda looks like a calcium deficiency...

only looked at 3 pics can we get a pic that is IN focus?

does it look like this?

looks you might have got some water on the leaves during lights on

the water acts as a magnifying glass

Yeah kinda, but the spots are more toward the middle of the leaves. ITs only happening on two so far. Happened on the first one about 3 days ago now its affecting a second one. I dont know if its water doing it because there was that much water on them maybe a droplet or two, thats it.

any water left on for more than a few mins can cause burning, as he said its possible

So the real question here is...is there any nutrient solution getting to the roots? 2.5 weeks old the plant needs nutrients now...before it was running off its cotyledons to get nutrients...if your bubbleponics system isn't hitting your root system the plants will just die...so you'll have to either raise the level up on things, or put a drip in, also fill in the rest of the space with hydroton so no light goes down through...you don't want light reaching your nutrient solution or roots

Like how many ppms? possible nutrients toxicity or ph fluctuation~
I doubt if it's from the lights, to much of it....
Some of your drooping could be from to much water or to often watered.

Well, I have added 1 tsp of micro and 1 tsp of grow from stealthhydroponics.com. is that not enough? i also mixed them separate. using luke warm water to dissolve the nutes.
