New Grower First Grow, first deficiency?

[Jivey]

Infirmary Submission - 10/19

Problem: Likely deficiency presenting itself on leaves.

-Medium/grow method: soil; Fox Farm Ocean Forest

-Feed and supplements used: 1 standard feed of Cal - Mag; no other nutes yet

-Water source: dechlorinated tap water

-Strain and age - Seedsman White Widow Auto

-Climate: 20 hours on, 4 off. High temp is 84 degrees and low 76

- Light used: HLG 260 QB 28” from plants

-Additional info: The leaves have had the curl for some time, but I just noticed the spot today. I haven’t added any nutes other than cal-mag yesterday, and the spot was there prior to the feeding, as was the curl. I’m thinking maybe Magnesium or Phosphorus deficiency, but I’m not sure. I was holding off on nutes until I had to, because I’ve heard OF can be hot for seedlings. I have another plant in there Buddha Seeds Purple Kush that isn’t having to be same issue. Any help is appreciated!

Don’t mind the runt closest to the fan. I know that ones a goner, I just haven’t had the heart to yank it, since it’s my first grow. The plant at the bottom right is the main one in question. That and the one next to it are the white widows.

Plants look OK to me but that fan is huge and pointed right at them. I don't see signs of wind burn, but seems a bit large to have directly pointed at them.

The little spots don't look like deficiencies to me. Leaves aren't always perfect, little imperfections here or there.

That little bit of curling wouldn't worry me much, but your temps are a little on the high end some times. Overall plants look fine and I wouldn't worry about them, seems like you're doing great for a first grow.

Always good to get a second opinion, but if those were my plants I would keep doing what I'd been doing.
