transplant before flowering?

Do you guys think its a bad idea to transplant shortly before flowering? I currently have them in 1.5 gallon pots and wanted to move them up to 3.5
I ask because the soil I have is Ocean's forest, and I'm worried it might be too strong for when i flower :O

thanks

Yes, transplant.

Or, depending on the pots you use you could "double pot".

Rather than transplanting, BushyOldGrower (BOG) cuts the bottom out of the present pot, and places it in a larger pot partially filled with soil.

This image shows this technique, with the smaller pot having had its bottom inch removed.

The double potted plant is now ready to put on some new roots.

Gl!

Ocean forest is the bomb digity throughout your entire grow. I love it!! Most definitely transplant before you start flowering as a rule of thumb but I have transplanted to larger pots during flowering (2 weeks in the latest for me) & have had no set backs. I don't do that anymore unless I must. I use 1.5 gallon planters & 3.5 gallon planters myself. I wait till my girls are 16" tall & then I transplant to my 3.5 gallon planters. On an average mine will double in size plus a few more inches. I always get 3 footers after the first month of flowering has gone by & then it stops growing & just focuses on packing the weight to buds & get frosty with trichromes. How tall is your plant now ? I grow fem ak48's from nirvana. What are you growing ?

Okay, thanks a lot guys. i was just concerned that the rich soil would potentially stunt the growth, due to it having nitrogen.
