These black dots (very tiny) have been appearing on my plant and are moving from the bottom up - very quickly. Flowering has just began and I need to take care of this before the buds really start to grow. Can anyone tell me what this is? Pics: (you need to view full size to see the specks) 1 - The main stem where you can see the specks concentrate around the bends of the stem 2 - A dead fan leaf (dead from nute burn, not this problem) that i pulled to show the specks. Look at the brown specks on the stem. These specks are very hard to scrape off and do not wash off. I can't find anything about these things by searching, so does anyone have any clue what these are?
Thanks for the reply, I can't really tell if it's something thats spreading, but i'm pretty sure it has been. I'm going to look at it under a magnifying glass tomorrow and maybe apply some 0.5% bleach solution to affected areas. I will also be buying neem oil as soon as I can and maybe some diatomacious earth.
bleach is not a good ideal are the spots brown purple or red if they are purple it maybe the start of p def if they are red it maybe the start of n def if they are brown then i,m not sure but you plant looks good so if it does not get worse the leafs look ok then you should be fine
Yea, the leaves are fine - its the stems that have the brown/black specks. I've looked thru all of those guides for deficiencies and diseases and pests - but I cant find anything about these specks on stems. I'm pretty sure its not an insect, because they dont move and can't be washed off... unless its burrowing in to the stem... idk - could possibly be aphids, but for some reason they aren't eating the leaves? Could be a fungus or something but idk why it would be specks. Idk, maybe its part of the plant... but I haven't seen it happen to any other plant online. No idea here, just brainstorming I'm gonna do a little testing tomorrow with a magnifying glass to get a closer look.
looks fine. your stems may be starting to darken and change color. all of my plants so far have done so and they've turned out fine
NEVER EVER EVER NEVER use bleach on your plants or near the soil. Use it to clean grow rooms and equipment but on a plant boom, your plant will die.
Thats good to hear, thanks. I'm still gonna check these out tomorow, but now I can be more assured that it is part of the plant. Ok, so no bleach, I won't do it. I'm just gonna get some neem oil later this week to try out.
