advice please

Quick question. I was given 13 plants the other day, all a week into flowering. They are all in 1 gallon pots (im guessing on the size), should I transplant them, or is it too late? I just bought a bunch of 5 gallon pails, a bunch of promix and a jug of growtek bloom. The girls are under 1000w MH... iknow, wrong spectrum, but i cant afford a hps till next month.
I just kinda jumped back into growing, hell, i dont even have a light shade or mylar up yet.

Any tips?

oh, p.s... they are "fast pine" an outdoor strain. wouldent be my first choice for indoor, but im planning on ordering seeds once these are done. I'll probably re-veg one and save it as a mom for next summer, i dunno.

thx

do you know how long they've been in the pots?

not too sure. they were started in beer cups, so im assuming theyve been in there for a while.

3 gallon should be big enough. Just don't fill the five gallon buckets all the way up. Be sure to drill holes for drianage. Make the hole ion your new soil the same size as the pot and water the plants a little just before transplanting. VV
