So the story continues... this grow is really an experiment for me to train one plant within my 4'x2' grow space to ScrOG vertically and use the SP250 light on its side. For the majority of the vegetative stage the light will be hung normally above the plant until a week prior to flipping the light schedule and initiating flowering.
The plant passed its seedling stage and has been vigorously growing albeit showing strong signs of over-watering and calcium deficiencies. It's really a transpiration issue which I have not solved yet. Increased distance to light as the plant may be growing too fast for its root mass. From feedback at Coco for Cannabis (CFC), it is a Cal deficiency and a young plant getting used to the grow in coco - quite common and not a sign of over-watering. Measuring run-off EC at each fertigation event as I increase the feed EC to monitor what the plant is doing/feeding.
Fertigation is now maintained at twice a day (at lights on and 4hrs prior to lights off period) to maintain the target EC. Light period is during the night time to better maintain heat/humidity conditions during light off period (which happens during daytime).

The grow setup includes ;
- Secret Jardin DS120W tent (120cm x 60cm x 180cm) placed inside the bedroom
- Mars Hydro SP250 LED light
- extraction fan - AC Infinity Cloudline T6 (gives me great control over the environment)
- ventilation fans
- aquarium heater for nutrients solution (for winter use only)
- small oil heater (for winter use only)
- small dehumidifier
- 20L Airpots (as final pots) and 3.5L general plastic pots (for seedling stage)
- Canna Coco substrate mixed with 40% perlite
- GHE Flora Trio as base nutrients and various additives
- pH and EC/TDS meters
- 2x Govee Thermo/Hygro meters (one at canopy, the other at the roots level - these allow for external monitoring and recording)

Some strain info from Royal Queen Seeds ;
An amazing mix of genetics background - Its true genetics are unknown. Some say OG Kush is a mix of ChemDawg with a Lemon Thai and Pakistani Kush. Others say that it’s just a special cutting of ChemDawg from the early 90s. The most obvious trait of OG Kush is its strong, unique, very dank, slightly citrus aroma, almost like fuel or strong detergent. The flavour of OG Kush is equally as strong and dank, with a long-lasting aftertaste.
Strong mental and physical high - OG Kush is an extremely strong cannabis strain, with most experienced smokers listing it as one of their favourites. The effect is as strong physically as it is mentally. Though its effect is like an Sativa, the strain's genetics are mostly Indica. The effect is as strong and complex as the flavour. OG Kush takes around 8 weeks to flower and on average the yield is 500 grams per plant.
Big buds with lovely tones - OG Kush is known to stretch slightly during growth but soon starts to fill out during flowering. Generally, it will reach a height of 90 to 160 cm. Its buds are large and dense, lime green clusters covered with a large amount of resin.
