i had this new seedling directly under a 400 watt hps at about 2-3 feet and noticed the leafs curling up. I removed it off an elevated tray thereby increasing distance and moved it to the periphery of the hps. is this a problem due to excessive heat or light or something else?

Am I overwatering these seedlings? (Coco Coir) Please help, Thank you :)
These seedlings are about 3 weeks old in Coco coir. I PH the water to 5.8-6.2 everytime. I was watering every 1-2 days as the top soil dried out. Have I been overwatering? How much/often should I water them at this stage and should I wait for them to perk up before transplant?

Yellow blemishes
1 week old seedling is starting to develop yellow blemishes on initial leaves. Soil is biobizz lightmix, PH 6.2 from bottled water with no nutes, 150w led light is at 50% and 25-30cm distance. Is it a cal-mag deficiency, light burn, genetics, or just too soon to worry?

What kind of deficiency? What should I do? By the way, they're autos.
What kind of deficiency do I have going on here? I gave a good dose of calmag last night. The first signs were the dark spots on the leaves. Been feeding ff bloom nutes every other day, 1/4 to 1/2 strength. started from the bottom. Leaves turn yellow and then dry up.
