hello
Can anyone tell me what.these brown spots are?
I just flowered a day ago and noticed this leave here.
But out of 8 this is the only plant with a leave like this?
Could it be soil burn?

Looks like calcium deficiency. It appears that @Covertgrower has posted a support ticket. Fill that out so the issue can be diagnosed.

Seeds from ilgm
Strain white widow
Led lights spider sf4000
Soil is kings soil
I just transplanted about 11 days ago so I have been using no nutrients for the past 11 days,ph at 6.3
But I think you are correct about calcium,for the past 11 days I have not added Calmag accept for last water on Friday
I totally spaced and then realized I should have been using calmag even when flushing.

Not sure if 6.3 is runoff or what’s going in. If that’s what you are going in with you would want to get that up to at least 6.5 Sometimes in even if you are at a sufficient level like 6.3 you may see it start to dip down in your soil.

Thank you too everyone for your input
Looks like yes it’s calcium deficiency
I just transplanted these babies about 11 days ago and was just adjusting ph and no calmag for 11 days ,I don’t know why I spaced not putting any in just starting so I tend to drop the ball sometimes.
But yes it all makes sense now
