These spots just showed up today. I had noticed the purple/red stems but I wasn’t aware that might be an issue. This plant is 18 days old. It has never had nutrients so that should eliminate a toxicity. I did get what I thought was a nutrient burn shortly after the plant started growing. I read where that could happen on new plants in a rich soil. Is this a magnesium deficiency It is only on one of the middle leaves. 2 of the lowest leaves have brown shriveled tips. Everything but 4 leaves look good.
I have accidentally gotten some water on my plants when I’ve watered. I thought I had brushed it all away. I guess I’ll take a wait and see approach. Thanks for the insight.
It doesn’t look like you really have anything to worry about. Be careful when watering and avoid nutes for a while. Keep an eye out for other possible problems and keep us posted.
A lot of people using OF don’t introduce nutes until they get near flowering, though things like silica and seed sprout tea will be fine in moderation at this point.
