First RDWC grow

Ok so these ladies first came up about three weeks ago, I will edit this with exact date, unfortunately only 3 seeds germinated so I started another one and as you can see she's behind a bit but the other three literally shot up in week and I also noticed that during their veg they hardly touched the nutrients, ppm didn't really waver until like November 13th or 14th at which point they depleted over night it seemed. On November 16th I did a water change and added nutrients listed in entry. All the nutes for early flower are included from veg plus a few more so I'm hoping that it won't effect the young lady too bad. So what do you guys think?
