Is this overfeeding or another more complex problem
qaogrw2020started grow question 5 years ago
This is my first Automatic plant culture. I've made some novice mistakes, such as topping the plants. They start flowering about 2 weeks ago, but the leaves are turning yellow with some brown spots. I feed with an old Nutrient I had here. Can that be the problem?

Your leaves turning colors like that looks pretty normal to me as I see it , it is mainly the bigger older leaves! Very common ,as they get dry defoliate them and she’ll return to the pretty plant you want lol

Yellowing and lightening of leavesMy back-left plant started to slightly yellow on me from the bottom up. Front-left is also lighter than the rest. Is this a feeding issue? Do they need more nitrogen or did I overwater them? Appreciate your answers :)Week 12

Yellow sugar leavesI am waiting for a low-THC strain to develop amber trichomes and I found two buds with these yellow sugar leaves. There is no bud rot, should I wait longer to harvest? Also, do CBD strains develop amber trichomes, or should I harvest now? Additional details available in growdiaryBuds. Other

Brown/yellow/purple leaves inThis started out as brown spots on big fan leaves and has turned into what you see on the pictures. I've been ignoring the discoloration until I was greeted by some wilted, dead leaves on plant #2 today.
I'm not worried at this point, just really want to know what's happeninga month ago

Fatal ovewatering? Will she survive?Ugh! One of my two plants Is dying. I suspect overwatering associated with some other issue I can't spot properly. 58 days flowering. It was my first flushing session, not a good start.
Her sister has no problem. Poked holes in the dirt, raised temp, maxed the fans. What else?2 months ago
