That looks like pH fluctuations to me. In coco coir is happens sometimes if the irrigation solution is suddenly at a different pH according to what I read.

Pests on leaves spotted pests on the top of new leaves. By investigating it seems they could be leafhoopers. They're few of them for now. Would neem oil be efficient? Should I be spraying the leaves and a grow medium too?

Leaves damaged I see like a nibbling of the leaves that I don't know if it is due to a splash with wrong doses of neem + soap or maybe to midges I think of soil that are manifesting more and more often. I have 3/4 plants like that, do I take out the three nibbles? and what can I do for midges?

Anyone have any ideas what this orange/brown mark could be? She’s in RQS easy boost and only been getting ph 6 water. I changed her pot yesterday, possibly something to do with that? Maybe different ph in new medium? Only one affected so far out of 3 plants. Thanks!

Should I defoliate these bushy auto's?These autos have grown a lot recently (on day 35 today) and are getting pretty bushy. Will this bushiness cause airflow/mold problems? I have a small oscillating fan blowing above the plants part of the day Should I defoliate anything at this point? Leave it alone?

Pitted leaves Hi I have a problem on three of my four plants. In practice the leaves are starting to be pierced I don't know if it is for the wrong mix of neem + soap that I gave a few days ago by mistake or some midges that have popped and that I'm trying to exterminate.
