Nope, not too much light for a 3x3. You should be able to hit your goal no problem with that setup. Might even be able to pull that with just one 190 depending on strain and veg time.
Yeah walls are reflective I order two all ready I had a 90w UFO and a 65 Hans my first led grow with two plants and only got 20grams each plant so I figured I need more light
I got 6.5oz on my first run with one 190 in a 2x3. Added a rw 150 and shooting for 3/4lb+. Depending on strain and experience 8oz with two 190s could be done in your sleep. Lol
