Discoloration Help

[cannabro_]

Any ideas on these bleached spots? I have 3 autos growing same environment same genetics. Definitely overwatered the seedlings at first. But not sure what this discoloration is. They are 2 weeks from sprout today. No bugs that i can find anywhere. the humidifier makes white dust. im adressing that.

Environment:
RH 60%
PH water 6.5
PPM 350 last reading and watering
Temp 78° during day. Drops about 5° at night.
happy frog only
No nutrients yet.
SF1000 at 30 inches and 60% per their guide for veg.

That is called "Variegation". It is genetic and is not a problem. Most plants grow out of it. I have seen plants with half of the leaves almost white.

The white dust you speak of is calcium from hard water. You want to use DI or RO water in your humidifier. It can cause a problem in the plant and will for sure clog the media in your humidifier.
