Feb 24 She's starting off her fifth week strong. I flushed her yesterday since she should be in preflowering this week. I did it outside and noticed a fly land on her, so I put a couple of sticky fly traps in the tent just to be safe. I'm not doing a lot of LST mostly leaf tucking and a couple branches weighted down with luggage locks.
March 2 end of week 5 she literally doubled in height from 8.5" to 17".
I gave her a heavy pruning/defoliation today in the lower branches, and then turned off the lights early so she could recover with 9 hours darkness instead of the usual 4.
Good luck! My first Fast Buds run is still going too (same tent as the Mephisto run we've been talking about.) The Fast Buds plant took off like a rocket! It will be interesting to see how your Jack does.
@delray_kevin,Thanks! I have a pretty tiny tent, 2'x2', so I decided to just do one plant this time and give it plenty of space. I was deciding between FB Bruce Banner and FB Jack and decided on the Jack since it's a shorter growing time, which helps in my situation.
