Late Flower Rapidly Yellowed LeavesThe yellowing leaves have definitely progressed quite a bit in this last week. Does this look like a normal natural late flower nitrogen deficiency? I still want to flush the plant, wondering if I should start the flush now because the leaves are already starting to get yellowed.Week 19

Younger leafs are discolering. What to do?This week my WW started getting pale? I tried to look on examples on the net of discoloring leafs. Is this a Zinc defecienty? She seems to be struggeling a bit because of the colder nights. Could this also be due to that? Looking forwards to your answer, dear question replier!Week 7

Lower leafs getting yellow tips and spotsI just noticed that the lower leafs are dying, while other leafs are getting yellowish spots. Is this some kind of nutrient deficiency? The leaf with the yellow spots is near the air intake.
They didn’t get any fertilizer except root juice since the soil is still somewhat fresh.2y ago

Leaves with yellow spotsWe have find some leaves with yellow spots in them. The tips on new leaves are also turning yellow. Is this nutrient burn? Searching online I found it may be due to pH fluctuations, although we use pH controller with ferts (before ferts only bottled water pH ~5.5).Leaves. Color - Yellow
