Climbing mount O.G. Kush

It has been a week of snap snap snap! let's call it accidental toppings - yes - multiple. The OG Kush seems to be quite fragile compared to other strains I've grown. Continued LST has resulted in me snapping off the end of the main stem and another major branch. Both days within switching the light regime. Now I have to fill up the net using lateral branches. Initiated flowering with an extended dark period (32hrs) prior to switching light regime at the beginning of the week - this practice is supposed to promote a faster initiation of flowering by the plant. Light green spots and other spots noted on big fan leaves, possibly a calcium or other deficiency. Spots are lighter shade, irregular though some are circular. End up turning bronze colour dust. No pests have been spotted during extensive inspections. The problem remains to older leaves only and doesn't seem to be affecting any new growth. I also think I may have some Nitrogen toxicity due to my CalMag solution having a NPK ratio of 6-0-0. Getting some low N solution this week so hopefully that will address any impact on the flowering stage. The plant still seems to be strong, forming strong branches and massive fan leaves. Growth is being tucked under the net to fill it up. Pruned a few stems and leaves from below the canopy which may never see the light of day. Run-off EC still remains below target. Tracking run-off volume/EC/pH at every fertigation event as I manage the feed EC to monitor what the plant is doing/feeding. Fertigation is maintained now to once a day (at lights on) 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.
