This week started with a flush to address persistently high runoff PPM (1400+) and unresolved calcium deficiency issues. The flush brought the runoff PPM down to 650, at which point I stopped and allowed the plant to rest for 24 hours. During this time, I also performed light defoliation to improve airflow and remove affected leaves.
The following day, I gave a light feed at 50% strength to gently reintroduce nutrients and encourage recovery. While preparing the feed, I noticed an unusually high pH in my tap water, which raised suspicions about my pH pen's accuracy. After recalibrating the pen, I fed the plant according to the updated readings. I also completed the lollipopping process, significantly improving airflow, and performed some LST to level the canopy by bringing down the taller branches.
Over the next 24-48 hours, I observed signs of some light nutrient deficiency, likely due to the flush and light feeding, as expected. For the next feeding, I plan to increase the nutrient strength to 75% and evaluate both plant health and runoff. Based on these observations, I'll decide whether to continue at 75% or increase to full strength (100%).
Finally, I decided to upgrade my pH meter to an Apera PH60, as frequent recalibrations of my current pen (a yellow Vivosun) have proven too tedious and unreliable for consistent readings.
Looking good there , I've got some bd on the go aswel and have had some deficiency and quite high runoff ppms from them in biobizz light mix even without using hardly any nutes yet and going into week 6, I've just repotted mine into final 20l containers with biobizz all mix so will be giving plain water with calmag for the next 2 weeks until they show me some signs but they are looking alot better now i got ppm runoff 👇
