Need advice on different leaf symptoms

[Chisan]

I have my bubba kush in a 5.gal fabric pot in my backyard. Its on the south side where it gets full sun from 6am until 5pm. I live in the northeast. My growing mix is peat,perlite, composted manure/hummus. The only time I fertilized was when I put it into the pot using dr earths all purpose plant fertilizer with mycorrhizae. I had some nibbling going on from insects so i used neem/dawn solution on them about a week ago. Today I notice more of my leaves are showing signs of stress can anybody help me pinpoint what it is. I was leaning towards nutrient deficiency but I want to make sure. my pH is seven. I am brewing some compost tea to use just in case it is a nutrient deficiency.

Very similar issue here in upper Midwest. I posted question Friday and no reply.

Have you tried anything since you posted?

I also have this happening on my leaves at the back of the plant.

Looks like a calcium deficiency, caused most likely by bad PH, or lacking cal-mag.

I still think they're hungry. (<<link)

With those burnt tips, soil might be too hot (too much nutes)....causing nute lockout/P deficiency (the spots)...happened to me recently, a couple good distilled water flushes righted the ship.

So should I feed them or flush them like @dreamgreen said?

 

[dreamgreen]

What’s the ratio of compost to everything else, for your medium?

I see the burnt tips, which goes to @dreamgreen 's point. But, when was the last time you fed? In the previous thread (I linked to), I thought it was some time in the past. If they keep getting worse when you're not feeding... it seems like it would be hunger. Lockout looks a lot like underfeeding. It's the same thing (acidity of the soil not allowing nutrients to be taken up. Or, no nutrients available to be taken up.).

That's what it looks like, back off on the nutes.

Looks like overfeeding to me.

pH induced lockout would look more like general deficiency. This isn't showing yellowing, or the leaves dying from the bottom up. The leaves are generally green, but burned. I'm going to go with too hot a soil. It's unlikely that any flushing will fix this, if it's a soil amendment causing the problem. This is why I decry 'organic' fanatics. If you do it right, it works, if you miss, it's hard to adjust in the current year.

Makes sense. In my case, i use only topsoil/rice hulls, with organic juice added to to water...easy to adjust.

Dam, Ill try flushing it with distilled water a couple of time and then leave it in the sun and see what happens. Here are some leaves I trimmed off

 

[OldManRiver]

Easier for us to help if you show the leaves on the plant, for future reference. It's important where they come from, what the rest of the plant looks like.

I don't think it's a good idea to remove leaves like that. If the plant is underfed (my opinion) or locked out from to much nutrients in the soil, those leaves still have nutrients stored in them. If the plant is cannibalizing its leaves for nutrients, and you pull them off because they look bad, then it has to cannibalize other leaves (more). The two lightest yellow ones (bottom right) might not matter. But, the others could still have had some value to the plant (IMO).

Plus, if you pull the ugly leaves off, you lose the ability to measure progression of the problem.

I posted them on the plant further up in the thread. I took them off because I dont think they will recover and their was a cricket happily munching on one lol

I understand what you are saying
