Aphids!

The aphids moved in due to weak plant and being easy target did not help. Is what I see over all going on.

You have what looks like a substrate ph issue. Too much nitrogen in flowering, and potassium deficiency. They look done growing. Any new growth will be fox tailing. Flush and call it. You missed your window, From looks in pictures. Plus nutrition burn. So I am gonna say you have ph issue in substrate from lacking proper run off and build up of salts making you substrate ec probably pretty high also driving the ph into drifting fast. W ok.i old be my diagnosis from looks.

I am currently facing the same problem.

Once I found the aphids I immediately removed as many by hand and then did a 3 day treatment with Dr. Zymes. I have them mostly under control. Some still are under leaves and on branches and I pick off what I can. I will be treating again in 2 days. Some branches the buds are fattening and hardening up while others are fat and fluffy as hell and others haven’t fattened at all and are fluffy as well. Now the leave edges are turning brown and they don’t have aphids under them. I started flushing this week as the trichomes are a little clear, mostly milky and very little amber. Anyone have experience with this and an idea to fatten these ladies up somewhat before harvest.
