24H in tap water, then planted into a CalMag and pH-buffered coco-perlite mix in a cup.
This will be a temporary early veg container, and the plant will be transferred to a permanent pot once the box is vacant.
Watered with CalMag-enriched and pH-adjusted runoff from the cup substrate buffering solution. Upcycling, I guess.
Yeah, her first pair of leaves if much, much wider than anything that I have seen on the two 80-90% Sativas I have grown before. Expecting this to be heavily Indica-influenced. But let's see, I'll try to put all my biases aside the best I can.
Pronounced Indica traits continue to emerge, as far as leaf structure and shape is concerned. I am not implying that this is a pure Indica, or even an Indica-dominant hybrid, just to be clear.
Accidentally exposed tips of two adjacent leaves to a moderately bright strip at a small distance — they caught the very edge of the light cone. I think it was exposed for just 1 light cycle, but the stress and minor damage was already visible by the time I noticed and addressed the situation.
The root cause of this problem is that I trusted the flowering and harvest schedule provided by the breeder. For the second time, with two different breeders, the estimate is off by at least 2 full weeks, probably 3. Hence I had to accommodate both plants in the same tent under the same set of lights, at least until I construct a dedicated nursery.
2nd grow in 70/30 coco-perlite mix* & very similar issues w. yellow/brown spots in weeks 2-3, then stabilizes.
*CalMag & pH buffered 6h @ 0.5mS, pH5.8, strained** & seed planted.
Feed:
W1: **Strained sol. + water 70/30, pH5.8
W2: AN M+G+B 1-1-1 + Simplex CalMag Plus 0.4mS
Help
Those little spots on that 1 leaf could be from a couple drops of water when watering, humidifier mist, or even debris that could of came in contact from opening tent, fans, etc
I see no other symptoms and your plant looks really great!
Keep doing what you're doing!!!
Finally transferred her to the permanent pot after evacuating my makeshift hanukkiah (see my first Humboldt Sour D grow, harvest week) and refurbishing and re-buffering the medium.
Some smaller root matter from the previous plant was still left in the mix, although I had tried to extract as much as possible. Was too tired and didn't feel like filtering sifting it any further, even less so blending the entire thing to shred the roots. Maybe it would have harmed the coco too. Let's see what happens.
Previous plant's roots looked healthy white at the time of excavation, so hopefully no infections. I Washed and sterilised the pot, but did not sterilise the medium, not to disturb existing fungi and bacteria so then can start breaking down leftover roots right away, while the new plant's root ball is still 95% contained inside "clean" nursery root ball medium.
I didn't picture it previous week, but I had used a ~400ml (14 fl.oz) tall plastic cup which I had Tungsten Himars-ed into a cup-shaped colander for proper drainage and root and soil aeration and ventilation.
In terms of the root system, while having been contained for a pretty long time, I think the plant had made great use of the vertical space, and will have no problem expanding laterally now. Previous plant had more of lateral root spread than vertical. For better or worse — no idea. Let's see what this one does. I think this time around I compacted the medium a bit more before transferring the root ball.
A couple more days in a makeshift nursery reflector while the Sour D is distributing and stabilizing its moisture before being transferred to glass jars for curing.
