anyone else familiar with this?
The longer it veg's, the more they do that. Cannabis is an annual plant. It's life cycle is completed in a single season. While that is the case. You can veg far longer then 3 months and still flower it out with no negative effects,,,,,,If you have the space.
looks like it started to flower and was revegged. Any pics of the whole plant?
I don't see that at all!
What I do see are 3 leaf sets.....That tells me the plant is not stable (stressed) and that can effect the plant developing the above condition too!
In easy terms, the plant, due to the stress it has been under is getting desperate to make "babies" as it feels it is in trouble and may not finish right..It is attempting to rush things and can't because of the light times not producing the bloom hormones it needs to actually bloom. It can be flowered like this but it will not reach the full potential of the plant. It will not "harm" the plant to flower in this stressed condition, in fact the plant will really take off kinda quickly when flipped - normal bloom time will be in effect.....I would not flower any plant until it throws 5 leaf sets. An indication that it is NOT stressed.
A pic of the whole plant would be more revealing on this. OR if the plant does have 5 leaf sets forming on the new growth - your golden!
Like I said. The plant will bloom out ok if not.
