4-5 autoflower growany advice helps

I have done many grows I'm doing a 57" by 57" tent with 4 auto flowers candy kush, cherry bomb, northern lights, and bubblegum I currently have a 600 watt mh installed with a 8 inch inline fan I'm ordering a 6 inch exhaust fan soon with carbon filer and also looking at a Apollo horticulture 300 watt led as well if I can maintain the heat here's a early pic from 4 days ago I'll update more gonna turn this into a journal

The veggies in there of course will be removed as soon as the auto flowers start getting bigger

Here's 3 of the 4 that popped 4 days ago

Update this is 5 days later

You will grow with the MH or just for veg right?

Just for veg I have a 600 watt hips well I got 6 but I'm just doing a tent this summer to get some personal cus I didn't have time to take care of a whole room.
