8 Ball Kush

@HazeyBobby, great. Thanks for that answer. I think I should bring my nutrient schedule forward by a week or 2 for the next grow in this case. I am using the BioBizz nutrient chart which assumes an 8 week flowering period, so I may be a week behind where I should have transitioned to heavier doses of bloom fertiliser. Cheers!

@eggman, it’s common for plants to exhibit a nitrogen deficiency during the mid- to late-flowering period - pretty much where you may be in a week. This can cause plants to lose leaves and reduce yield as the nitrogen exits the old growth for new growth. Best way I have found is to gradually switch over to bloom fertilizers to ensure that you don’t run into a nitrogen deficiency during flowering. This essentially allows the plants to store enough nitrogen until the end of the flowering period. I'm not sure adding Nitrogen after deficiency symptoms in flowering aids. I maintain a high dose of N until pistils show (which is typically 2-3 weeks after switching the light regime).

@HazeyBobby, Thanks a lot for the advice! Is the leaf colour expected as early as week 5 of flower would you say?

Thanks for the support @HazeyBobby, i'm pretty excited
