Quick Summary: moved and transplanted around day 18 into 5 gal. airpots with fresh ocean forrest, flowering began around day 24, thought I maybe had some nutrient burn, more likely cause is phosphorous and/or cal/mag deficiencies, three plants in the home stretch, O has a bit longer
Day 50 Update: Watered and took some pictures last night.  Not much new.  Pretty sure they have massive deficiencies instead of any burn.  I may chronically underwater/underfeed my plants.  I'm still learning.  This is my fourth grow ever so there's still lots to learn.
Day 51 Update: Meant to water today but didn't.
Day 52 Update: I spent a while with each plant and took some pictures/video when plant O was out of the tent.  You can see some pretty clear brown spots on a fair bit of the shorter two plants.  S is all kinds of ugly, but who knows, maybe still put out a decent weight.  I fed twice in a row now and added some CaliMagic (forget the company name) this time.  I read about how when there are stronger lights or MORE lights, the plants can burn through phosphorous rapidly, so maybe that's the issue I had.  Either way, about day 40 seems like when the nutrients can be more steadily increased.  The shorter two, V and P, have about 2ish weeks so that will likely be their last feeding.  S too probably.  O, on the other hand, has several weeks left but is looking otherwise really solid.  Hopefully I got enough nutrients in early enough in that plant's flowering that it won't show any deficiencies.  It's a monster too!  38 inches to the top of the spire.  The other three are 25, 21, and 19 inches still so likely their final heights.  I kept the tallest as the plant height for the diary because the top end is good to know for other indoor growers.
Day 53 Update: No news.
Day 54 Update: No news.
Day 55 Update:  S, V, and P are the three shorter plants.  They are all starting to take water a bit slower.  They didn’t *need* water tonight, so I’ll give them another day.  O, on the other hand, is a monster!  Probably needed water yesterday.  Filtered tap, about 2 gal for O tonight.  Food next time for O also.  Others are in the wind-down so we’ll see.  Pics added from tonight.
Day 56 Update: Nothing to report.
