I think this is problem with coco buffer. Try to use more cal-mag and change your nutrient solution. Lower potassium, raise cal-mag.
Problems with coco pH - always about wrong watering and wrong composition of the nutrient solution.
p.s 5.8 pH its not bad for vegetation.

You are spot on. Coco range 5.5 to 6.5. You couldn't be any better. Your run off is smack bang in the sweat spot at 5.8 and 5.9

Yellow blemishes1 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?

Yellow Leaf Tips with Brown Spots – What Could This Be?One of my plants has yellowing tips on some of its leaves, and there are also brown spots forming on these yellow areas.
Any ideas on what could be causing this? Could it be a nutrient issue, or is it maybe related to pests or environmental factors?

Slight lightburn?First pair leaves on left plant turn slightly lighter, first sign of yellowing a bit. Also I think they are a bit in a V/praying shape.
2 full weeks old under 75% of 200W leds about +-45cm. Should I dim them a bit more/hang higher?
Other suggestions maybe?
