Harlequin CBD

xchdave Week 1 – Seedling Stage (Days 1–7) Harlequin CBD seedlings emerged alongside the Super Lemon Haze and are sharing the same environment. Transplanted straight into 2.5L pots filled with a super coco and perlite mix, early growth has been slow but expected as they focus on building out a strong root system. A humidifier was added on day 4, bringing RH up to a much more seedling-friendly 60–70%. Temps have been steady at 23–24°C with light intensity set to ~280 PPFD. So far, the Harlequin seedlings are showing healthy coloration with no signs of stress or stretch. With roots now taking hold and environmental conditions optimized, I’m expecting more noticeable vegetative growth heading into week 2.

xchdave Harlequin CBD – Week 2 Update (Day 14) The Harlequin seedlings are now two weeks old and settling in well. 🌱 Growth: Plants are establishing nicely in the 2.5L pots, with steady development of true leaves. They are showing healthy green color overall, with no significant signs of stress or deficiency. Growth is slightly behind the Super Lemon Haze, which is expected given Harlequin’s genetics — more moderate vigor in early veg. 💧 Watering: No water added for the past two days, as the medium still retains moisture. Root zones are being encouraged to search deeper, helping establish a stronger root mass. 🌡️ Environment: Temp: ~25°C Humidity: 60–70% PPFD: ~320 Ventilation: AC Infinity T6 running at speed 1 — providing good fresh air exchange at this early stage.

xchdave Well we run into a bit of trouble the last two weeks, what I thought was over watering symptoms was actually caused by under watering. This means that by continuing holding off from watering, I made the plants issues worse. By the time I corrected my mistakes the plants were already stunted and showing signs of nutrient deficiency. I continued to struggle with the plants for a week and they did improve. However not as fast as I would have liked. This prompted me to change the entire course for this grow. See I'm normally a coco and synthetic grower. I don't have these problems with coco because coco can be 100% saturated and still have access to adequate air. I was hoping to try my hand at organics this run but given the above issues I decided to revert back to what I know. And well, the plants are back to being healthy, all be it very small for this stage of a grow. It just means we've got a bit of extra veg time before flipping to flower and that's why I love photos over autos. I transplanted to 15L autopots with the 50/50 of coco perlite and feed at 1.0 ec and a pH of 5.8 until runoff. My nutrients of choice are: Yara Kristalon Brown Calcinit Epson salts I've used a few different brands of nutrients in my time and this is by far the most economical solution I've found and dialed in properly gives just as good as results as any name brand nutrient out there. If you're buying bottled nutrient you're paying for water. This set up makes for an easy grow, especially when we add the autopot bases and turn the reservoir on. Anyways thanks for reading my dairy and continuing to follow along, I'll be sure to keep this dairy updated going forward.

xchdave The CBD plants have shown good recovery from earlier minor stunting. This week I topped both CBD plants, and new shoots are forming well. I turned on the Autopot system after giving a manual feed of 1.5L with light runoff. They're now being fed the same 1.3 EC reservoir as the Super Lemon Haze. Overall health looks great—leaf color is vibrant and growth is vigorous. They are slightly shorter and bushier than the Lemon Haze, as expected for this phenotype, and are holding moisture well with the Autopots now running. Lighting was also increased to 450–520 PPFD, which they’re handling well. Very promising recovery and growth heading into the next week.

xchdave These girls have bushed out incredibly well. They're enjoying the autopots and the environment seems dialed in perfectly for them. And as such have exploded with growth this last week This coming week I'm going to defoliate, scrog, take cuttings to clone and hopefully get ready to flip to flower!
