Hello, I planted 1kg of oyster mushroom spawn along with 4 kg of wet substrate. It has been 16 days and although the mycelium has completely taken over the substrate, I don't see any pins developing. I've kept the temperature in the room to 25oC and the humidity level is 70% . I am attaching a picture for reference.. hope yo hear back soon
Those jars appear to be sealed. Pins cannot form unless it is exposed to fresh air (the more accurate term is CO2 exchange). With that small amount of substrate, it will be important to spray it with a fine mist several times per day. If all goes well, you can expect to harvest half of your initial substrate weight worth of fruiting bodies (also depending on substrate make up).
As a cultivator, myself, I prefer a humidity controlled tent. This can be as simple as a horticultural greenhouse tent and a fogger in a jug of water, with a fan blowing inside. Hooking this up to a cheap humidistat will automate the process. It doesn't have to be that intense, though. It can be as simple as a tote with holes in it, and perlite in the bottom, kept saturated with clean water.

Wondering if I can have jars of growing mycelium and fruiting cakes at the same time
I find that exposing mycelium to some light helps it to colonize faster, in spite of old knowledge that says otherwise!
I have colonized species over several genera, both, in darkness and in fruiting conditions. What I have found is that most will perform the same or better, in the light, as long as your moisture is on point.
The exception is with Agaricus bisporus...
If you want that pristine, white, button- Those bad boys need to be grown in darkness. Otherwise, you will see quite a bit of brown coloration.
I'm a senior in high school and wanted to grow mushrooms for my senior project.
This is a subject that would require quite a bit of a response. In order to do that, I will direct you to some articles that will help:
