Sativa hybrid seedling

Hi there,

I am growing a Pineapple Express (Sativa Dom) and it’s at day 6 from germination at first they were growing fine but when the first true leaves grew in I noticed that the side of one of the leaf blades was turning yellow and one of the new growth leaves is also yellowing at the tip. I know this is nutrient burn. And I already did a light flush to get rid of some of the excess soil nutrients. I also read that sativa plants are more difficult to grow and are sensitive to nutrients. So the real question is will the plant be ok once I transplant it to a 3 gal fabric pot with 60% FFOF and 40% perlite? I used distilled water to perform the light flush I hope that was ok. I have attatched some pictures. Also the stem is bending a bit so I added more soil. Will it straighten it back up on its own or should I support it?

right now the PE is in 20% FFOF, 60% FoxFarm Light Warrior, and 20%Perlite.Misting every other day with distilled water only.

Looks to me like it's going to be just fine for a transplant when the time comes.

The best remedy for unwanted stretch is more light. When you transplant, you can plant it deep enough to not be top heavy, too.

It’s under a marshydro ts1000 led grow light at 45% intensity. At 18” height from the soil. Will it get nutrient burn again from the FFOF once it’s transplanted due to it being a Sativa Dom?
