Just installed new spider farmer light last week. Idk if I have the brightness too high or I have a deficiency like calcium. Please help. These brown dots just showed up yesterday. Week 5 of flower. Any help would be great.

What do you have your light height and intensity set at?

What nutrients are your currently feeding and at what dose?

This is light burn that happened at a messured 800 ppfd. Her sister next to her is taller and was at 900 ppfd and no burn. Same plants from the same packet of seeds.

Had to back the light down because the plant on the right is a sissy weak wussy plant.

What is the Fox Farm Micro and Macro? Are you talking about the Fox Farm Cultivation Nation 3 part Micro, Grow, and Bloom?
If so, the Micro is supposed to have calcium in it but the other 2 do not.
You did say you just flushed, if you didn't have signs prior to flushing then I would just continue your feed and if it starts progressing, supplement with an actual calcium supplement.

I believe it’s the dirty dozen schedule. It really seemed it popped up after the flush. Cal meg is included in the schedule. Just gave her some in her feed.
