Hello! I am a new grower and I want to hear people's thoughts on my plants. I have 5 Red mandarins and two auto flowers, all 4 weeks old. I think they mostly look great but the one at the bottom center has been looking sad for a few days and the leaves developed brown spots.
THoughts?

Under-watered possibly? What is the pH of the soil runoff?
Have you fed any calcium or magnesium?
I would check the articles on deficientcies.
Gotta have picks of what the spots look like. . .
Hi there and welcome, yeah she does look a bit droopy. Is that one of the auto flowers or the photo periods?
Can you get a close up picture of that plant and let us know what kind of soil she is in and what you have been feeding her. PH and PPM readings would be helpful if you have that information.
