Is this Fungal Infection on my Hoyas?

Hi #GregGang! Checked my lovely Hoyas today and noticed these marks on them. As always, google and Reddit (sometimes) arenโ€™t helpful so I figure I might bother some #greggers to help me out! ๐Ÿ™Œ๐Ÿฝ

Is this Fungal Infection? I may be overwatering recently due to the fact that my brain canโ€™t remember the last time I wateredโ€ฆand Greg is being a little funky, so a few plants have had a little more water than others ๐Ÿ’€๐Ÿ’ง๐Ÿ˜ฉ

Edit : No buggies / pests found around these plants since these are in a seperate room ๐Ÿ˜Š but I am currently fighting Aphids and Mealies in my bathroom ๐Ÿ˜ญ

Iโ€™m also wondering if itโ€™s because itโ€™s adapting after transplanting to soil! Sometimes I know plants will feel conflicted when grown in water and then suddenly placed in soil. I donโ€™t transition since I donโ€™t have issues (usually), but wondering if this may be the case!

Tagging a few people that may be able to help ๐Ÿซถ๐Ÿฝ @jaysjungle @HoyaAddict @sarahsalith @Gordo

Nothing to stress about hun ๐Ÿ˜ƒ just oedema in Hoya. Maybe water a little less in volume but a little more often otherwise I wouldnโ€™t stress too much ๐Ÿ˜ฎโ€๐Ÿ’จโค๏ธโ€๐Ÿฉน

Fungal Leaf Spot
Botrytis fungal infection covers hoya leaves with masses of gray or light-brown spores. As it progresses, the leaves become spongy to the touch. Its love of humidity means the fungus is most likely to infect the hoya's innermost foliage. Botrytis is most active during the shorter, cooler days of fall and winter. Control it by lengthening the intervals between watering your hoya plant to reduce humidity.

bacterial Leaf Spot
Hoya leaves displaying pinhead-sized, watery yellow or light-brown spots are in the early stages of Erwinia carotovora bacterial leaf spot disease. Warm, humid environments encourage the spots to spread, developing a slimy texture, irregular shape and sunken centers with deep-brown margins. Water-filled blisters may occur on the foliage's undersides. In cool, dry conditions, the spots become paper-thin and tear easily. Control measures include watering your hoya from beneath early in the day, giving it adequate air circulation and growing it at a temperature no higher than 70 degrees. Destroy a severely infected hoya to protect other plants.

Small, black or green specks on a hoya's leaves signal the presence of shoreflies. The 1/8-inch, black insects deposit these droppings when they settle on the leaf tips. These pests feed on leaf or soil algae without harming a plant but they may transmit disease. Shoreflies avoid algae-free hoyas. Watering your hoya only as necessary discourages algal growth.

neem oil can be applied as an organic fungicide, but it's also important to address any issues that led to the development of the disease in the first place. Avoid misting your hoyas when conditions are cool or at night. Also, rather than watering over the foliage, pour water only onto the soil.
Nothing to worry about! Let the soil dry a little more between watering.
