Thanks for submitting your photos and care details!

Assessment
Your plant is not getting adequately watered.  Bottom watering only works if the plant has a sufficient root system to actually “drink” up the moisture near the bottom of the soil.  A plant with a compromised or immature root system won’t do well with bottom watering.

Also, if you always bottom water, the soil near the top of the pot will be become dry and compacted to the point where it resists taking in moisture, resulting in dying roots in that section of soil.

Lastly, on a personal note, I only top-water (as in, pour into the soil with a watering can or directly from the tap) – I have never needed to bottom-water any of my plants.

A Monstera with a healthy root system should perk up from droopy in a few days after watering.  Here’s my Monstera 2 days after repotting and giving it a thorough showering:

Environment
In order for the grow light to be effective, it must be measured at the leaf: it should measure at minimum 200 FC at the leaf and be kept on for at least 12 hours a day.

More on measuring light in a grow light context.

Effort
WHEN to water: whenever the soil is about halfway dry.  HOW to water: thorough and evenly soak all parts of the soil and let excess water drain away.  I generally do not recommend bottom watering.  Use a 3-1-2 fertilizer on a regular basis otherwise, you will experience rapid leaf loss (more than usual) after a few months.  More on fertilizers HERE.

Expectations
After a few cycles of thorough soaking (from top-watering), your Monstera’s roots should reestablish themselves and cause the plant to perk up in a few weeks.  Good luck!
