I had 4 awesome girls went on vacation for a week came home to some girls that are getting sick. Please help

[AutomaticTimmy]

I have a 5 by 5 tent
4000 watt kindled light 30 inches above canopy on 18/6
5 gallon fabric pots
Filtered intake and exhaust fans
2 air moving fans in tent
Everything is on monitors as far as temp,humidity,co2
I have grown outdoor for 20 years and this is my first indoor experience.
I grew autoflowers for the first time this summer outside and was so impressed I wanted to start growing auto's indoor.
Fox farm ocean with super soil.
Just ph water until preflower and I use BB EVERY OTHER WATERING
I also use Bigfoot mycorrhaize every week for the first 4 weeks.
I like organic and the autos I grew outdoor in 3 gallon fabric pots did well until the last 3 weeks. That's why I stepped it up to 5 gallon pots thus grow hoping I wouldn't need additional nutrients. Thanks in advance for any tips or help.

They look fine to me?

If your asking will they make it to harvest without a top dressing? I doubt it. It is always a close call with 5 gallons but I see more losers than winners.
