Hey ddxsinxcosxdx :thumbsup:

I personally would not transplant!! A 5gal bucket should be great till harvest.It is just hard for me to imagine being root bound in 5gal unless the plant is
a year or so old.

The 8.2 ph water is way too high !!! If it is coming out at 6.8ph, you have a lot of nute buildup in the soil.

I recommend a good flush with ph adjusted water around 6.5, followed by light feeding of a quality fertilizer.

I also really hate to disagree with Weedhound on the transplant, he has such great information to share, but on this I do. Sorry Weedhound!!!

Good Luck and please wait for more replies, my Ideas are just how I grow.
