My auto babies

[Potheaded]

I am now in the 5th week of my auto flowers ( 2 pineapple glue auto, 1 blackberry, 1 northern lights, 1 six shooter and 1 lsd) all autos. My lsd and northern lights had issues coming out of the seed. The skins stuck to them and held them up. The lsd is about to die and the northern lights isnt far off. The others are healthy but growing real slow. Im using a 400w mh at 21" and plenty of airflow. Temp stays around 78° hum at 50%. Soil is happy frog organic. What can i do? They should ba about to flower but no signs yet.

Are all these plants in week5?

Those plants seem very immature for 5 weeks.
My autos usually flower in the 6th week using DWC, and then get huge.
You might benefit from the higher humidity that the Vapor Pressure Deficit chart recommends.
For an air temp of 78 F, which probably means a leaf temp around 72 F, VPD dictates a humidity between 55%-85%, with the sweet spot at 70%.

Have these plants lived their whole life in those bags or did you transplant?
How much and how often are you watering?
Water source?
Your temp and rH are close enough that I don't think that's whats slowing them up, but obviously something is going on. You say in the 5th week. Give us a day count? And is that from seed? Emergence? Or first true leaves?

Lastly, has had issues keeping they're soils pHing on the mark, you may want to test the soils pH.

The plants are severely stunted if in week 5. Personally I would dump them and start again. That is just one opinion.
