Two Week Old Seedling, Pale green discoloring

Hey guys,

On my second grow now after an unsuccessful batch of autos. More information below including photos, but noticed Lemon Candy had some pale green discoloring on new growth this morning. Let me know your thoughts, not sure if it's nutrient deficiency and time so start slowly adding feed.

Plant: Lemon Candy (710 Genetics)
Medium: FF Happy Frog (30/70 perlite to soil)
Container: 4" pots
Watering: pH'd (6.5-6. tap water that's left out for 24+ hours
Light: LED Samsung Quantum Board 100w
Distance: 22 inch
Intensity: 50%
Temp: 73-74
Humidity: 45-55%

Hi, first i think you need to repot\transplant and cover those long stems. Also try to bring your light closer to the plant to stop the stretching.
I’m not sure about soil grow but you might want to start feeding.

Just curious, is your led light from HLG?

Also they need light, theyre stretching trying to find more of it. A bit small for two weeks as well.
Unsure about your soil as I’ve never used it but I think happy frog should have enough to last 4-5 weeks at least.

you have a 100w light at 50% intensity. They need lumens mon

It is an HLG. They've grown a lot already since photos were taken fortunately. But main stalks still a bit thin and Lemon Candy still has pale spotting.

Agreed, shouldn't need to feed just yet. But thinking of transplanting to 3 gal pot next week.

Can you explain a bit more? I can measure lux with the poor reader I have. 1500 lux and space is 2x2x5.5

Seems a bit early to transplant, especially with how fragile stem is. Good tip covering with more soil.
