Idk if it’s coming out of the leaves or dripping down from the buds. When I touch it, it’s sticky and stinks like burnt pine, or maybe just an overwhelming pine scent that disturbs my nose the smell isn’t enjoyable imo. And only 1 plant out of 5 is weird to all the same strain, all 8 weeks into flower . They were grown outdoors until about 6 days ago, I got paranoid about the rain, because I found some bud rot on a few plants.

Hi pal, found this somewhere else after being intrigued by your issue:

“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.... Take care brother!!”

Thank you, it’s getting bad and on other plants now, I leaned over 1 of the plants a few minutes ago to check the trichs and there were brown smears all over my chest. It’s like automobile grease. Maybe it’ll be a good thing.

I hope so! Surprised nobody else has offered any information, someone must have seen it before? Unfortunately I haven’t, other than the standard transpiration when leaves overlap.

Hopefully somebody else will chime in with some information for you!

Same thing going on with both plants downstairs...both a different strain. I'm thinking maybe it's the nutrient regimen I'm using. Very strange.

I found out why my plants are emitting sap from the leaves and dying...and it's not guttation, it's a reaction from thrips. The thrips are sucking all the juices out of my plants...I was hoping it was this guttation, because a plant won't die from it...but thrips are another thing...just killed two nice plants 5 weeks into bud...
