Potential problem with first grow

these 3 leaves are looking a bit lighter or dusty. The plant was transplanted to a 2 gallon bag yesterday and hasn't grown noticeably in 24 hours. Some leaves are curling up at the edges. The top left one has slight yellow or brown. I suspected too much light but it's already 13,000 lux or about 333 ppfd so it should be low enough. It's not overwatered for sure.

plant numbers

Age: 19 days
strain: girl scout crack
Medium: started in solo cup of miracle gro potting soil. Transplanted to happy frog in a 2 gallon pot.
ppfd: 333
Light: Led full spectrum red blue white yellow ultraviolet and infrared.
Ph: around 6.5 in the runoff.
nutes: whatever was in the miracle gro after. sifted it fine and soaked it in a gallon of water for an hour. The runoff is 800ppm higher than the water I put in.
Temperature: 80-82 degrees
Relative humidity: 55%
Air flow: small fan aimed at plant and an air filter with a 7 stage hepa filter rated for a small apartment.
Grow space: walk in closetView attachment 2181557
could this be powdery mildew? A deficiency? Just dust? Light burn? Nutrient burn? Any ideas?

Can’t tell anything from that pic. Miracle grow soil isn’t the best, and by soaking it you probably leached any nutrients out of it. Don’t chase ph in soil grows, and ppm’s/ec isn’t nearly as important in soil as it is in hydro. Happy frog is very light on nutes, so you need to be feeding. When you say you sifted it fine, is that the MGrow or the HF? .

The miracle grow was sifted to be used as seed starting mix. I wanted a fluffy easy to root in soil. I soaked it because I've been told miracle gro is too hot. The runoff seems to have a lot of dissolved solids so I don't think it's hungry. Now that it's in happy frog I'm feeding a grow fertilizer at 25% starting next watering
