12/12 from veg?? What would happen?

Okay so I have two Auto #1 that have been in flowering for almost 3 weeks now.

I have a 400W Super HPS running in the tent at 75% (300W) for temp control. 400W 100% gets too about 86 degrees. at 75% it stays from 80-82 lower depending time of day.

I have two photoperiod girls in the tent, they both got overfed with nutes over a week ago and they are both recovering as we speak. new undergrowth is growing in etc.

Question is:

If I switch to 12/12 right now since the two girls in flowering at AutoFlower strains and the other two aren't even done with veg since they are recovering, no where close actually, would I even yield much off of these 4 girls?

400w with 4 plants = 100w per plants.
which is enough to penetrate alot of growth.

yield depends on alot of things tho.

nutrients/ph issues/heat issues/ etc etc etc -- lots of variables.

you said you had 2 auto + 2 photo.

your yield with the auto plants will decrease when you put em on 12/12 (they are suppose to run 20/4 or 18/6 or 24/0)

how old and how tall are the photo plants? (this plants will produce and start flowering once induced)

you will yield yes -- but who knows how much.

can we see some photos?

They are like 2.5 weeks old. BUT I overfed with nutes one week and had to cut off all the growth since they were clawing/twisting.
SO now they look as if they have been out of the soil for maybe 1.5 weeks.

First photoperiod is roughly 9cm x 6cm x 8cm
Second is roughly 8cm x 6cm x 6cm

So not big at all... I just think I may have to move back home within the next... 2 months and need to finish these up as fast as possible.

BUT it is day 49 from seed for the Auto #1 and apparently they finish up around day 60? So should I just keep it going at 20/4 for now and then maybe do a 12/12 once the autos are done?

2 months to finish up the grow?

i can tell you right now that your photos wont be finished in time.

photoperiod plants takes roughly 8-12+ weeks of flowering (depending on strains)

i would personally keep the lights running at 20/4 in favor of the 2 auto plants - maximizing plant growth and yield.

remember that 60 days is just an estimate OPTIMAL CONDITION by the breeders.
- harvest the plant by trichomes not by days/age.

you can then flip 12/12 to get your photo to flower
- by this time they should have recovered from the nute burns.
