Oh no! Please tell me these are not new bugs!! (SOLUTION ...

I just found what appear to be dew droplets on my #BrazilianPricklypear . They feel like tiny salt crystals, and if them opened and was sticky.
.
I did the best I could with photos. Please tell me this is normal and not another pest!!!! Def does not look the same as my recently discovered Scale bugs. #gregteam

@HyggeVibes so, Iโ€™ve been looking online and it seems like it could be that it was โ€œinjuredโ€ and is leaking sap, which then crystallizes once excreted from the plant. It seems as though they can excrete a milky-colored sap if they are injured (whether it may be a fungal infection, physical injury, too much sun, etc.)

Has anything happened to it lately?
My Drooping Prickly Pear is perfect.
My other smaller BPP does not have the same crystal beads on it. Perfectly normal.
@HyggeVibes it looks like scale or mealy bugs to me.

Here is how to treat it. Scale, if treating small infestations, responds well to pruning and rubbing alcohol. For larger infestations, youโ€™ll likely need to discard your plant.

Mealybugs can be treated by pruning, and dabbing a rubbing alcohol soaked cotton swab on the infested areas.

They look so similar, either way rubbing alcohol will take care of it.
I agree that it looks like scale.
FYI for scale you should be able to scrape it off with your fingernail and then treat.
@KikisOasis & @MeganO , ladies , thank you.
Iโ€™ve gone through massive Mealy Bug infestations at all of their life stages. Def not mealy bugs.
As for Scale, I just went through this earlier this week. @Kiersten helped me identify.
I know the pics are terrible, it this looks completely different.

Itโ€™s tiny clear bead like droplets. Hard, like a sea salt crystal. Some were in clusters. Some just a single droplet.
Almost like a little bead of a hot glue gun droplet.
They popped right off in my fingers. One of themโ€ฆ. Just one, opened and was sticky. All the rest were hard and could not be crumbled.
Like crystals were forming in the plant.
Zero resemblance to the Scale that I just removed from my large cacti,
Iโ€™ve tried Googling it, but I keep getting mealy bugs. Itโ€™s def not mealy bugs. Itโ€™s not cottony. Itโ€™s not the adult gross big (of which I squished hundreds) and not the tiny white flies.
The Scales looked like little fossilized crustaceans.
Itโ€™s neither.
Any other thoughts???? ๐Ÿฅฐ
My first thought was honeydew. Honeydew is a sticky substance that secreted by pests. But when you said it was crystallized, it threw me for a loop.

I know spider mites, scale, mealy bugs, whiteflies,and aphids can leave behind honeydew... so maybe it's leftovers from your previous pest experience.๏ฟผ ๐Ÿคทโ€โ™€๏ธ
@sarahsalith interesting. Iโ€™ll Google that.
@MeganO , ahhhh. Not really, just that the plant has always struggled as Iโ€™m trying to get it healthy.
@sarahsalith , so this link seemed somewhat helpful; https://www.newprocontainers.com/blog/4-bizarre-plant-symptoms-stump-interiorscapers/

But I still donโ€™t have a conclusive answer.
@KikisOasis @MeganO @sarahsalith , ladiesโ€ฆ. This might be the answer:

https://www.lovelyhouseplants.com/white-crystals-on-plant-leaves/

And from what I can tell, itโ€™s natural and harmless.
THOUGHTS??
@HyggeVibes Iโ€™ve never had guttation cause crystals? ๐Ÿ‘€
โ€œThe water drops stay on the leaves until they evaporate, leaving mineral deposits behind. When a large amount of these minerals accumulate on the leaves in a relatively short time, they become noticeable in the form of white crystals.โ€


I wonder if itโ€™s because I have hard water?????
@MeganO , right???? But I think thatโ€™s it. I just did a terrible job explaining it and getting decent photos.
โ€œErrors in watering and fertilizing can either cause guttation to happen way too frequently or load the water up with way too many minerals, with both scenarios causing white crystals to appear on the leaves.โ€
I think I caused it with Hard Water.
@MeganO - so, in answer to your question, againโ€ฆ.
Itโ€™s my fault. Watering with Hard Water caused this Guttation.
@HyggeVibes I wonder if the color is also darker/more milky because itโ€™s a cactus which has a white sap naturally. ๐Ÿ‘€ I love problem solving stuff like this lol
@MeganO ๐Ÿค” hmmmm interesting. Iโ€™m def learning a lot.
This has taken quite an interesting turn! Science strikes again- I love learning about the plants. I am rereading this and I wonder who this blogger is, but it seems to have put you in the right direction!
@sarahsalith YES!!!! It was such fun figuring it out~ and that it wasnโ€™t a bug!!!!
Making the switch to filtered water for all my cacti.
