Hi to everybody
My name is Dan i have a problem with my 3 week old plants.
I grow them under 600hps, 12inch from a lamp.
I had a small deficiency of N few days ago, but that problem was sorted.
Ph of soil is 7, water between 6-7 (do my best to reach 6.5).

there was a problem with humidity so started spraying leaves with water for a night. I did it every night and started 3 days ago. I sprayed the well with a water.

Today morning one plant got some black shadows/spots on bottom leaves. The other three are okay. Problem is on Ice cool, i had a loon with magnifying glass, but cant see anything, its only 10 times. Will have microscope x30 in the end of the week, but for now dont know what to do.

2 days ago i moved plants to bigger pots and mixed soil with worm casting.
I have no idea what has happened.

If u have some ideas please help me.
Thank you
