Any idea what these bright spots can mean? Plant is 2 1/2 weeks old and those spots show only on older growth.

Looks more like a pH issue. Was the coco washed and buffered? Many brands claim to already be....how well they did so is often debatable.

Add CalMag or Manganese? Still slightly discolored and veiny leaves on week 6
Calcium or Manganese deficiency? Last week had what I thought was early calcium deficiency. Gave it a dose of CalMag but now not sure if it’s still Calcium or possibly Manganese. I do mean manganese but I realize it could be a CalMag or Manganese deficiency as well.

What's wrong with these plants? Light leaves.
My husband's project: He uses the nutrients very experimentally and I cannot say for sure how much he used. Looks like CalMag is in order? What else might be going on? Thank you in advance.

Nute burn or gnats?
Is this nutrient burn or fungus gnats? I started to see signs of my leaves starting to lighten. So I moved the light away and it didn’t solve it. So I started flushing, which seemed to help at first but because the soil is always wet I’ve got lots of fungus gnats flying around.

Deficiency?
I noticed this spot on one of the fan leaves. It only appeared in the last couple of days. I have been feeding small amounts of calmag and biobloom. I looked at deficiency charts but I’m unsure. What could it be?

What’s wrong ?
This plant has displayed this yellowing in a couple of its older leaves. It hasn’t gotten better with the exclusion of nutrients it doesn’t seem to be hurting the growth of the plant as it has continued to grow over the past week. Is this something I should be concerned about?

Haven't watered since sprout, one of the 3 seedlings (super silver haze auto) seems to have an issue, I think it might be overwatering because I may have soaked the soil when planting.... It seems to early to be any kind of deficiency....
