This week marked the transition to Jack’s 321 formula at 80% strength (literal 321), and the plant is responding well. The week started with a water-only feed to help dissolve residual GH salts and prepare the medium for Jack’s nutrients. The switch itself happened at the next feed, and the plant has since adjusted seamlessly to the new regimen.
The soil pH, which had been a persistent issue, is finally stabilizing. Runoff pH is trending downwards slightly but remains manageable. Feeding at 6.1-6.2 seems to hold the medium steady, giving confidence that nutrient uptake is back on track. Runoff PPM has risen slightly compared to previous feeds, but nothing concerning—likely just the result of introducing a new nutrient regimen.
The canopy is steady, with leaves showing no new signs of distress. Older damage remains visible, but it feels like the plant is moving forward. Pistils are slowly transitioning, with about 30-40% starting to amber, and resin production is evident everywhere. Branches are drooping a bit under the weight of the buds, so supports are in place to prevent any stress. Overall, the environment feels dialed in and ready for the next stage of ripening.
Note: Nutrient amounts are in grams per gallon, as a g/gal category is not available.
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 👇
