Premature flowering - advice???

[HighonPottery]

Have a family friend with a premature flowering problem this year. In years past we have not had much issue with planting in the ground late may - but this year the plants want to flower early. Not sure if its weather related or plant related (revegged/monster cropped). Located at 38*N in CA

Plants were all nice and healthy monster cropped plants in 5-10 gal pots when I gave them to him. All various strains some of which are new to me: Tutanchommon, Bluedream x pink, Tradgic (TW x magic), Purp diesel, Great white. They were happy and vegging awesome only one or two showed signs of leftover flower but seemed headed toward vegging- because of the great weather we weren't too worried as light hours are long and days are very warm. All were at least 24" tall and very bushy looking like they would yield several pounds each this fall.

Fast forward to now - he tells me they started going wacko and wanting to flower in June of course he couldn't have told me this a few weeks ago when it would be easier to fix, but that didn't happen.looking for advice to be able to keep these going for the season without pulling and replacing.

I told him to try and get a light on them at night to disrupt dark cycle and to feed with a good amount of nitrogen to promote fresh growth. Not having seen them yet I was unsure to advise to prune anything at this point until I get some advise. I do not have pics to share but would like to see what others suggest for keeping this years crop successful. Any help is greatly appreciated!

If he used ant fertilizer that could of been it, and what kind. I dont know about anyone else but i use 20-20-20 for the first stage of the marijuana growth then switch it to 10-52-10 as it's budding, maybe check that out?

Very interesting, and this is with a combination of strains. Revegged plants are never the same, hence the crazy monster cropped growth. I consider this to be an epigenetic change, where some formally inactive genes have been switched on and they've stayed that way. So if some flowering oriented genes are already switched on, it makes sense that the plant will more readily slip into flowering mode.

So try to reveg them again in the hope that they'll grow significantly more vegetative structure before flowering again? The days at your latitude are about fouteen and a half hours long now. Maybe it will work. If the situation allows it and the plants are big enough it might be possible to just go with the flow to get a short and quick but small early harvest. Good luck with this.
