I've had this Monstera for close to a month now and received it as a cutting. At first I kept a humidity dome over it to help with acclimating, and after about 4 weeks I removed the dome (also because the substrate was staying wet for too long, root rot?). However, it has been almost a week since then and I've noticed today there is some discoloration and what appears to be thinning on a part of the leaf. I've placed the humidity dome back over the leaf in case that was the cause.

Here's the information about the plant's environment/care:
Lighting: ~3ft underneath a 36W Sansi grow bulb
Nearest Window: ~2ft away from a NW facing window
Fertilizer: None yet, still acclimating
Potting Mix: 50% orchid bark, 30% perlite, & 20% cactus/succulent soil
Watering: Watered (only once so far) when the top inch of substrate feels dry. Last watered May 18th since the substrate is still damp, though it is almost time to water again (hence why I took the dome off).
Humidity: Averages about 60%, lowest it gets is 55% as I have a humidifier
Temperatures: Since I've had it it has not dropped below 64 F (18 C) and goes up to 80 F (27 C) at its worst.

The last picture is what the leaf looked like the day I took the humidity dome off (June 4th)

What's wrong with it and what can I do to test? I know they are notoriously fickle but I've tried to be as careful as possible and not over or under provide for it.

I saw lots of posts on here about Alocasias facing downward and the general consensus seemed to be that they were receiving too much light, but I saw a few comments suggesting that the cause could be root rot. This, in turn, has made me paranoid that my Alocasia 'Dragon Scale' has root rot.

I repotted the plant two days ago because all three of the plants in the photos were in a singular pot which they had outgrown. Are they drooping because of the light or is it root rot? One of my Alocasia 'Pink Dragon's is in a higher light spot, was purchased from the same seller at the same timem and it has not drooped once all while it actively pushes out a new leaf.

They were repotted into a chunky aroid mix I made consisting of orchid bark, perlite, charcoal, and soil (I forget the exact ratios since it has been a while since I made the mix). I fertilizer every 1-2 waterings with a quarter strength solution of fertilizer and reverse-osmosis water.

My monstera deliciosa has been happily growing an aerial root as horizontally as possible, but I'd like to guide it down into the soil before it gets unmanageably long. I don't know why it insists on resisting gravity but it seems rather content with doing so. I've tried curling it down toward the soil but I'm afraid of breaking it as it is not particularly flexible.

Is there anything I can do?

I noticed this little bulb at the base of the plant a day or two ago. It doesn't look like a new leaf, one of which can be seen emerging from the center of the rhizome. Is it a flower beginning to form?

I started growing early girl tomatoes a few months ago and they've done relatively well with some fruit already along the way. However, early on I noticed black/brown spotting on some of the leaves which I thought were sunspots as I'd been watering overhead, so I trimmed off the damaged leaves and have been watering at the base since.

Despite that, these spots have returned which leads me to believe it is fungal in nature, perhaps septoria leaf spot or early blight? It seems to primarily affect the larger, lower leaves, but even some of the new growth at the top has a few spots. What is it? What do I do?

(I'm growing them in the San Francisco Bay Area)

Thanks!
