Looking for opinion on pics

Haven't grown in a few years. I'm used to using T fives and HPS. This is my first LED grow from start to finish. Plants about 23 days old. Hlg 650s zkittlez glue soil is a mixture of perlite Happy Frog and Coco Canna. I'm seeing small white spots that I've never seen before that almost look more like residue some comes off some doesn't. almost like a watermark. A little bit of canoeing but I've raised the lights and dim the 650s down to 50%. Just curious looking for thoughts and opinions

What and how do you feed/ water her?

I gave it my first feeding about 4 days ago maybe five days ago using General Hydroponics. I used calmag and micro and used about half of the recommendations on the chart. I water about every 3 days

I agree it looks like a watermark. And if you got the leaves wet while watering her I can easily see it leaving a residue behind. Especially with the cal-mag. I grow DWC so I only top feed for a couple weeks. I would try spritzing her rather heavily with distilled, or R.O. or bottled water, something with little to no contaminates, put a fan on her and see if you can rinse it away.

I have three rather large fans in there now and I spray multiple times a day but maybe I'll try with bottled water this time. However I am seeing some of the little water marks on a couple of the smaller plants to that I haven't said yet and that is a bit concerning

I really don't know dude. Sorry.

Check for thrips as well.

I always give my girls a "Garden Safe Fungicide 3" treatment at first transplant, only transplant for me, it seems to kill or ward off anything that gets in my tent. It is also a fungicide, insecticide, specifically a miticide. If it is thrips(I don't think it is) it will handle them also.
