Should I repot before flowering? advice sought

I repotted my girl last week from a 3 litre (1 gal) pot to a 10 litre (3gal) pot and in the past two days her roots have hit the bottom.

Not sure exactly when was pretty shocked TBH to see them roots when I picked her up to check for watering but given her growth I kind of suspected which is why I checked.

My flowering lights come next week and I plan to put her straight into flower when they arrive.. so that gives me a week before flower. I am under the impression that transplanting during flowering or close to flowering is a bad thing, not the end of the world and preferable to root bound ofc, but nevertheless something to be avoided if possible.

I am using bag seed so I do not know the strain.

My question is should I:

A: Repot today into a much larger container approx 50 litre (13 gal pot I think we have)
B: Wait until mid flowering to repot
C: Not repot at all and the spurt in growth will not be a problem for the roots.?
D: None of the above, stop being a noob and here is what you should do...

Personally I think A as then I should be able to get to end of flowering without anymore transplanting and stress but being a noob I don't know all the factors so some confirmation or advice would be appreciated.

Repot in a week right before you flip her. That way she will stretch as much as she wants to, and reward you with bigger buds. I personally don't see the need in transplanting right now, why give her a week to use precious root space? Let her use the space while she stretches. As its a bagseed you can keep her in the pot she's in but she won't reach her full potential as she becomes root bound. Hope this helps a bit. Peace and happy growing!

there is a big difference between roots hitting the pot, and being rootbound.
Therefore I think C

Thanks for the advice..to both of you I'll do it when I switch to 12/12

i would do it a couple of days before switch to much stress ie. transplant and light switch cant be ideal.

read plenty of the topic today prob too much tbh... end result is next grow I will be timing my transplants better

I used to transplant from 5l into a 10l for flower and experienced problems due to not enough root room. I'm advising from experience, hence my original answer.
