Wien Bridge Oscillator Not Oscillating at 5kHz With Op Amp and Active Load—What’s Wrong?

Hello,
I'm a student in my third year of Electronics university and so far I've designed only a few regulators and some amplifiers and now I wanna try and design an oscillator. I've read some things on the internet and watched a few videos on youtube and I built a schematic. The problem is... it doesn't oscillate and I have no idea why.

I have the capacitors and resistors for the positive feedback so I can get f = 5kHz. I have an op amp with an active load and a second stage. What am I doing wrong?

I'm sorry if this is a silly question but I don't know what to  do to make it work, I'll get attached the schematic and the transient simulation.

https://en.wikipedia.org/wiki/Wien_bridge_oscillator has useful explanations.
You have +IN and -IN swapped: The base of Q2 is the inverting input, and the base of Q1 is the non-inverting input.Since you have R1 > 2*R2, the output oscillation should saturate, giving clipping of positive and negative peaks.

Thank you, I'm coming with an update.
I got it to oscillate and I have the right frequency, but... I read that if I can put 2 diodes like those in the schematic I can "adjust" the amplitude, but I actually want it to oscillate between [-0.3 : 03] V. I tried modifying every resistor and capacitor, how can I lower the amplitude even more? I'm getting around 500mV...

I also uploaded the images because it's hard to read the photos, also... I'm sorry for making the schematic hard to read.

It is my first visit to your blog, and I am very impressed with the articles that you serve. Give adequate knowledge for me. Thank you for sharing the useful material. I will be back for the more great post. Thanks for the blog loaded with so much information. Stopping by your blog helped me to get what I was looking for. areatrend coupon code

For lower amplitude, try replacing the silicon diodes with small-signal Schottky diodes or germanium diodes.Alternatively, you could passively attenuate the output with a pair of resistors.
