Is this nute burn?

Is this nute burn? I used the same soil, water, etc., as with my other plants but this is a different strain and it definitely reacted differently.

I used Pro Mix for dirt and used Fox Farms Big Bloom for nutes, and used it sparingly. I flushed the planter with clean rainwater today until I was sure fresh water was running out.

Anything else I should do?

Too soon for nutes and ditch the foil

Like REALSTYLES said its to soon for nutes. It looks like nute burn to me and get rid of that foil that can also cause burning on your seedling especially foil that has creases in it.

too soon! and doesn't foil create hotspots while barely reflecting any light at all?

I just put the foil on the for the photo, I had to use a hand-painted planter for that one and didn't want anything recognizable in the shot. Foil just looked cleanest at hand. I'll know better next time.

And I guess it was too early for Nutes, with my regular plants I always used a half teaspoon in a five gallon bucket of water when I wet the dirt in my pots before planting. I'll cut that out too from now on.

Thank guys, I appreciate it a lot.

Well pro mix has no food in it so you were in the right direction in feeding it. Unfortunatly it looks like you fed too much. You did the right thing by flushing but id be weary of the rain water until you check the ph. It may need to be adjusted for soiless. They might take a while to recover but they seem to not be dead yet. Ride it out and feed at zero to minimal feed while in the wee state theyre at. Then start to bump it up.

Thank you @Alienwidow. This plant is the first time I've planted anything besides the strain I've done before, and it's just fine. This one however, looks awful. I'm hoping to do a fully outdoor grow this summer. I live in a rural area and have 100 acres, but we rent the pasture space so I have to be creative and guerrilla with my placement, just so nobody sees it and rats on me.

I'm hoping to do a soilless indoor grow this fall. I saw a hydro setup I really liked, and I've seen 30/30/30/10 setups with coco/pearlite/peat or vermiculite/compost or soil. I'm hoping growing indoors this fall will give me more experience with things and help me decide what my preferred method is.

The plant looked a lot better today, I'll get a picture tomorrow. All my other seedlings had dirt from the same bucket and water from the same source. I'm not sure why this particular plant had issues when 28 others didn't, but it seems to be doing better now that I've flushed it out.

Thank you everyone, I appreciate it and my plant appreciates it too!
