Hey, bagseed vegged for 10 weeks now in 2nd week of flower. Was topped a while ago for clones, but all my clones died. I count ~23 budsites just in the upper canopy with more in the lower foliage. Im on bloom nutes now. Should I still be using Grow Big too? Under 400w CMH in 5gal pot, any idea on potential yield?
Looking pretty good so far, but it'll be impossible to guess the yield. There are so many factors that go into it, especially the genetics of the plant, that it would be impossible to put a number on it. That being said, looks like you should have a pretty healthy yield as long as everything keeps going well!
You should probably try swapping the MH bulb w/ an HPS if you can. Definitely switch over to some blooming nutes just like what the poster above said. You want the plant to switch it's energy production to focus on growing the bud sites and developing large cola's rather than expanding leaves and growing stems.
