First grow - RQS Royal Dwarf

Have had some challenges this week. In my lack of experience, I have struggle to discern whether my plant is deficient in nutrients, suffering lockout or approaching harvest. Symptoms were yellowing leaves... The cause of which can be, of course, many different things. I decided to flush last week, thinking that a nutrient lockout was most likely. Leaves less yellow this week so think it may have done the trick. I have spent some time researching and considering flushing as a technique to improve final bud quality. I have decided that there simply isn't enough evidence to deny my girl of nutrients at a critical phase of her growth. I am therefore continuing a reduced feeding schedule of - 1mls topmax - 2mls BioBloom - 1 scoop biosys ecothrive - 2.5mls Cannazym. And, unless indicated otherwise, will continue with this schedule up until harvest. Today I have tested PPM of the run off and measure it to be approx 1050ppm. I will measure again in 24 hours to monitor change after a feed. Purchased a 60x microscope and am able to see that 90% of trichomes are still clear. I am therefore anticipating at least another couple of weeks before harvest. Buds look fluffier than I'd like, but resin and trichome production haven't disappointed. I'm hoping that over the next few weeks the buds will continue to fatten. 19/11/2021 - Day 79. Have a few days off so have managed to catch some photos in day light. Have also uploaded a video. Feel that she isn't particularly happy... But on the other hand, she is showing the resistance and ability to adapt to less than ideal growing conditions; as promised by the strain genetics. Plenty of trichs, plenty of resin, plenty of buds. Just need them to fatten and fill out for maximum yield and quality. 23/11/21 - Day 83 - Still some deficiencies but she doesn't seem to be using much water so reluctant to feed at risk of overwatering. Noticing lots of new pistil formation. Looking frosty, but all trichomes still clear. Temperatures dropping to around 2°c overnight here. Managing to maintain temperatures around 10°c in the shed. Appreciate that this is too cold for growth but she seems to be coping with it well. I think that a gradual reduction in temperature has been tolerated better than fluctuant or sudden drops would be. Fingers crossed that her hardy nature keeps her strong. Fed today: 1mls BioBloom 2mls Topmax Half scoop Biosys Ecothrive Filtered water - pH 6.5, TDS 320 Run off 953 TDS 29/11/21 - Day 90 - no sign of any amber yet. Still mostly clear with a splattering of cloudy. Really worrying about the night time temps now and holding out hope that it doesn't die off before the trichomes mature.
