Day 2 of flower, 39 overall (i think). My best girl already has pistils popping out. I've switched to predominantly 2700K temp. CFLs: 1 105w, 1 65w, 4 42w. I've also got a 65w 6500K CFL for some spectral balancing but I'm guessing the one and a half hanging UFO LEDs are supplemental in both total light and light spectrum. They're looking pretty good but still the one in the back left looks like she's having some kind of trouble with her new growth. It looks kinda like the mosaic virus but its wearing little holes in the leaves. Not sure whats going on. I don't think it's spreading but the front gal might have caught a touch of whatever this is on one upper fan leaf. Of course this could have been from the light falling on these plants and scorching em for the 5 seconds it was on top of them. not sure. right now i'm working with just plain ole R/O water; gonna hold off on the nutes for the first week then pick up with a reduced strength FF soil schedule. I'm also going to give the girls some microbe brew this evening which reminds me, i need to calibrate my ph meter. I'm in FFOF but my soil readings of late have been towards the 7 mark; it doesn't seem like anything is getting locked out but that may be whats up with my sickly gal. again, not sure. I'll let the microbe brew sit down at 5.8, the lowest end of the pH spectrum for soil (per Cervantes instruction). Pretty healthy looking and good vigorous growth taking place;
Since I've added some light to the mix my temps run high. I've got 'em back down to 77 with the closet door open but they pop up to the high eighties (86-87) when I have to close up the tent at night. This was the first dark period so I just got my first set of data about the dark period stats: 63F lows with 68% humidity. I'm not gonna worry about the humidity because I'm gonna run a heater outside the closet during the dark period to keep the temp between 67-69. That should also help a little with humidity, dropping it hopefully a couple of percentage points. That should establish my environmental norms as a temp range of 67-87 and humidity range of 65%-49% with the average lights on being 78F and 50%.
This earthbox has made life easier on the one hand by making watering kind of a non-issue in terms of whether or not the girls will get watered. They wont be overwatered if I apply nutes lightly by hand watering but it does bring up a whole host of questions:
1) I've read that cannabis likes to let its roots dry out to go through successive wet/dry periods; the earthbox doesn't ever really dry out completely because its a wick system: will this inhibit or weaken growth?
2) In order to prevent over watering I only use <2L H2o on all three plants. Are the girls getting enough nutrients? Its iffy for me to water whole gallons of nute-water into this system because i don't want to over water and drown the roots/cause root rot but I also don't want these gals to be deprived of nutes they would otherwise use.
3) when to start adding nute water and at what strength without knowing how much has been used from the FFOF? I'll go by regular soil guidelines and just start up the feedings schedule in a week or two but pretty much by the end of preflowering I'd like to be on the bloom regimen.
this should be an interesting grow since it's some nontraditional light sources and some not traditional container gardening...we'll see how it goes.
