Indoor Growth Slowed to Crawl

Up to the past few days my plants have been growing as I expected indoors.

Now the plants are pretty much stopping growth, or growing very slow. There's no sign of stress, and I have been keeping the environment the same with 24/0 and I'm using SugarPeak Nutes.

The problem that comes to mind is not enough light, the room is about 60 sq ft although the plants are using about 1/3.

I am buying another 1000w for the room because I would like to grow these 9 a lot larger than your typical grow, probably veg up to four feet.

????

Also the larger straings are at 20-22 inches (Kush and Pineapple) and the smaller strain (GDP) is at 12-15 inches

what is the temp in there? Could be a lot of different things

maybe co2 how is the ventilation in there??

sounds like heat stress, work on your vent, you have plenty light.

the room temp is around 70 degrees but it is hard to keep it the same temp, it can change from 59-79 more often than I'd like

I think the ventilation is pretty good at 450cfm turned to half power on a dial for exhaust and 188cfm intake.

The one problem I think there could be when I built the room is that the intake is about 4 feet above the exhaust and the in-room air circulation may not be good enough, but there should be enough going in and out.

Would it help to add some ducting to get the fresh air to the bottom of the room?

I've got a thermometer that is right at the top cola under the light to monitor the heat from the light and it's not too hot.

The heat does randomly change from 60-78 throughout the 24/0 light cycle, not that often though maybe a few times a day. I keep it around 68 at the top cola as it's a little expensive to keep it much warmer.
