So these spots have just appeared on my Blue Cheese about 4 or 5 days ago about the same day (before) I transplanted them from cups. I figured some sort of deficiency and it’s not gonna be a problem... I’ve search forums and pictures different things it could be but nothing that looks like what I have going on. It’s in a tent with two other plants that do NOT have these spots on them. I’ve been watering them all the same with distilled 6.2 ph water. But I did water with calmag and silica on 3/28/2020. Planted in 50/50 FFOF and coco, under 2 600W LEDs full spectrum, at 20’ above the canopies. temp during the day is 85-89 and the RH has been consistent around 50. So why does one have it and the others don’t? I thought maybe genetics also but idk. I hope it’s nothing. I attached a photo of all 3 plants also, Blue Cheese (Left), Blue Dream (middle), Blue Haze (right). Thanks in advance.
