Critical Mass CBD Auto #2: Our younger lady continues to show off a completely different growth pattern! She is noticeably taller and more open than #1, with longer internodes, narrower foliage, and plenty of flowering sites along her branches.
One interesting development has been a gradual lightening of her foliage, particularly over the last week or so. While some of the leaves became fairly lime-green, they remained flexible and healthy-looking without significant tissue damage. Her flowers continued developing throughout this period, although she remains a little behind #1 in overall bud development.
Toward the end of the week, we even started noticing some green returning to portions of her canopy, which was encouraging!
Tent-Wide Updates: Week six has been all about maintaining stability and allowing these two Critical Mass CBD Autos to settle into flowering!
Both plants are now fully established in their AutoPot systems, with the reservoir providing our primary nutrition through Ventana Plant Science. The AirDomes continue operating during the light cycle, and both containers are maintaining consistent moisture.
One of our bigger adjustments was moving to an 18/6 lighting schedule. We had previously been running 20/4, but decided that a longer dark period might be beneficial as the plants progressed through flower. Since our primary goal is quality rather than maximum yield, I am perfectly happy giving these ladies a little extra rest!
We also continued keeping our light intensity relatively conservative rather than pushing PPFD unnecessarily.
Nutritionally, we gradually settled into a flower-focused Ventana Plant Science reservoir recipe. With #2 showing lighter foliage, I considered increasing nutrients or adding Cal-Mag, but ultimately decided against introducing unnecessary variables. Ventana Support already supplies calcium and magnesium, and I wanted to give the plants an opportunity to respond to a consistent feeding program.
Our reservoir recipe during this period included:
One Gallon of RO Water
Ventana Plant Science Structure: 0.5 ml
Ventana Plant Science FlaVUH: 1 ml
Ventana Plant Science Flower: 3 ml
Ventana Plant Science Expand: 0.5 ml
Ventana Plant Science Support: 6 ml
Target EC: approximately 0.80–0.95
Target pH: 5.7–5.8
We also introduced our first Stash Bloom application alongside Mammoth P, continuing the supplemental feeding approach we previously established with Stash Base and Blend.
Rather than adding organic amendments to the AutoPot reservoir, I prepared a separate, diluted root-zone drench and applied it from above. Both plants received approximately 1.2 liters, after which I removed the runoff and cleaned their AutoPot trays.
The plants responded well following the application and cleanup, with noticeably improved leaf posture and continued flower development. While I cannot say exactly which adjustment contributed to the improvement, I am happy with how both plants are looking!
One thing I am really enjoying about this grow is observing how differently these two plants express themselves despite being the same strain. #1 has maintained a compact, bushy structure with larger developing flowers, while #2 has grown into a more open plant with numerous smaller flowering sites.
Both are beginning to show some early resin development, and we are seeing plenty of fresh white pistils as the flowers continue to build.
Outside of that, there has not been much aggressive intervention this week, and that's exactly how I want it!
Moving forward, the goal remains simple: keep our environmental conditions stable, maintain consistent nutrition, avoid unnecessary stress, and allow these CBD autoflowers to develop at their own pace.
Onward to bigger flowers and hopefully some beautiful CBD-rich medicine!
