Grand Daddy Purple

Noticed plants were requiring quite a bit more frequent watering, with some wilting occurring within 24 hours. Pulled inside Solo cup out for all four seedlings and discovered all were completely dense with roots, completely filling the Solo cups (all four were root-bound). I was not particularly prepared for this to occur so quickly, but recognized the need to get them into larger containers as soon as possible. Mixed 20 gallons of FF Ocean Forest with perlite at a ratio of approximately 3:1. Inserted solo cup in center of each planter to create a hole, top-dressed soil with earthworm castings, and added mycorrhizal powder to root balls and final planting location. Quickly transplanted to 5 gallon fabric planters and performed a thorough watering to run-off, at pH 6.5. Did not check pH of run-off, but waited 24 hours to take post-transplant photos. So far, very little indication of plant stress, though I'm sure it will take several days to adjust in their new home. Difficult to say how things will move along this week- could be slow because of the transplant, or could be fast because the roots finally have room to breathe. Ideally, I would've waited to create a week 3 entry until much later in the week, but the immediate need to transplant on day 1 of week 3 was significant enough a development to update the log. Update (3/25- Day 19): Have not watered since transplant due to plants appearing to have everything they need for now. I'll probably water them tomorrow. The surface soil is dry, but it's still slightly moist when you sink your finger into the dirt. For now, I will not be using any nutrients other than verifying correct pH and a little CalMag based on some orange mottling observed on one fan leaf. Overall growth appears to be accelerating, with some plants moving faster than others. I suspect this is just the individual genetics, nothing "wrong" with them, just ever so slight variations from plant to plant. Update (3/27- Day 21): Plants responded well to moderate watering with 6.5 pH water, a small amount of CalMag, and a small amount of blackstrap molasses. Each is putting on their fifth set of fan leaves. The transplant did seem to slow growth slightly (though negligibly), but I also reduced PPFD immediately after transplant in the hopes of mitigating any light related stress. No significant changes to note for the end of week 3. No further spread of the orange mottling noted in last update. Considering swapping out the 1kW metal halide for the Hortilux HPS lamp, mostly for electrical efficiency, but also to gradually increase PPFD in the hopes of stimulating a bit more growth. This may cause some stretch, but the plants are very short and bushy for their age, and a little more node spacing won't necessarily be a bad thing. During week 4 I will be seriously considering topping between fifth and sixth nodes and some light LST to better expose lower branching.
