I've seen it. My WMD that is coming down soon was "delayed" cause she was topped at 10 days and then at 3 successive nodes. I've also had it happen by topping right after they show hairs. So far I have had pretty similar results across the different things I've tried, but I've also had plenty of environmental and nute issues along the line as well. I've been averaging an oz a plant, though the individual plant weight is overall on an upward trend. I only planted my first seeds on July 1 so I'm definitely still learning.I always sow in final pot. They look like they'll grow out of it.
I read somewhere about autos that were delayed like yours, timelines being
slowed down while they were not growing. The evidence was anecedotal
but hopefully they will grow out nice. Worth a shot.
