Hello all, first post here. Recently started listening to the dgc podcast and it’s an awesome community. Love seeing how well everyone gets along here. Makes a seemingly ugly world feel a little bit brighter. Anyway I was in my indoor garden the other day just inspecting everything and noticed what i thought were bugs on the leaf stems of only 1 plant, i used me amazon special bluetooth microscope to take a closer look and I dont know what to think. Never seen it before, doesn’t look like any bug I’ve ever seen. Looks more like sap leaking from the stem. Plant was grown from seed from a headband cross under hid lighting with a fairly consistent environment.
Oh, it’s 100% a bug; but I’m not sure what it is. Kinda looks like a mite but it’s weirdly tall. If you’re on IG I’d DM @bugladysuzanne and ask her. She doesn’t like pictures like this that aren’t super clear but you can see if she’ll give you an idea. She’s a friend of mine so tell her that @dtom420 referred you to her. Hopefully she can help. She’s (Suzanne Wainwright) the leading entomologist in the cannabis industry and you can trust her ID 100%. If I don’t know what I’m looking at in my garden, she is the ONLY person I trust.
Hope this helps!

No bug, just guttation.
Thanks a lot man! I’ll definitely ask Suzanne about it and share the info I get from her. I dont see a bug there but I was more concerned it was damage from a bug that I have yet to discover. Appreciate the advice and huge thanks to pointing me in the direction of an expert entomologist I can check with on it.
What your describing is called Guttation, and what your seeing is a sap exudate…. At night, transpiration usually does not occur because most plants have their stomata closed. When there is a high soil moisture level, water will enter plant roots, because the water potential of the roots is lower than in the soil solution. The water will accumulate in the plant, creating a slight root pressure. The root pressure forces some water to exude (most oftenly) through special leaf tips or edge structures, hydathodes, forming drops. Root pressure provides the impetus for this flow, rather than transpirational ascent. This sap exudate can be clear, tan, brown or even blood red(The red colour is due to haematin compounds and anthocyanin pigments that naturally build up in some varieties; The red colour may also indicate a nutrient deficiency, notably of nitrogen, phosphorus, potassium, or magnesium) This sap usually contains a variety of organic and inorganic compounds, mainly sugars, and mineral nutrients, and potassium. Upon drying, a white crust remains on the tissue surface. Guttated sap exudates most commonly exude from cannabis, along both sides of the leaf axil, where the petioles attach to the stem. Though Guttations typically exude(in most plants) through modified leaf stomata known as hydathodes, in cannabis guttations most commonly exude at the leaf axil, or another part of the stem via a stoma ….. It’s no worry really, but that sap is effectively a delicious meal for any would be insects and pests, so I would seal the wound with wax just like JK said to keep from attracting any unwanted visitors..
This is an excerpt from an article I came across on THC farmer awhile back. I hope it helps.
You’re correct.
look like scale bug
I’m going with sap guy on this.
There have been many posts asking about this process. Here’s the last one. https://www.dudegrows.com/guttation/
At first sight i thoughr it was scale but i have never encounter in on cannabis , but after reading comments i agree its sap
