Newbie build, with two autos - Mexican Airlines + Blackberry - DIY build

It's roughly been 4 weeks since I started, I had to take down the temporary build I started with and I just finished setting this up last week or so. It's still under construction. I am content with the build so far. Unfortunately, the tempt tent killed one plant (blackberry auto) I had to put this baby (Mexican airlines auto) on the balcony to get some natural sunlight/air/water. Which actually helped her recover. Trimmed out the dead leaves. I am a bit worried about the heat though, been reading about it a lot (any comments are welcome). Today I installed a new fan on top near the lights to push the hot air at the top towards the exhaust outlet. Hopefully next week I'll be able to get out (corona curfew where I live) and get two more fans. She's a bit too small for a 4th week grow, unfortunately I am a noob. I messed up and trying to recover at this time.

- I water every 24 hours or so, not a fixed schedule. I check the substrate for moisture etc... The last plant died due to overwatering, so I am super careful about this now.
- Seeds are from fastbuds - 100% germination

I am using FAMURS 1500W LED GROW LIGHTS
Grow box size 2x2x3
I bought the lights for a bigger tent/build. unfortunately, I could only get this done at the moment due to material/space and budget restrictions. Light's hanging through the ceiling of the box so that I am not wasting any headspace. There's an exhaust above the ceiling to keep the light vented properly. Also the light leaks will be patched up once I can get out of the house to buy some duct tape.
