New growth chlorosis and necrosis mid leaf and tips... help

[papapot]

So I'm having mid to bottom leaf necrosis/chlorosis. I'm running a high pressure aero at pH 5.9 but it was at 5.7. I also had foliar sprayed 3 days ago. Could that caused these issues? It's in I see it on 4 out of 6 plants thanks guys. I'll answer anything I can to find the reason for this.

Looks like early damage from either broad mites or russet mites to me.

What did you foliar spray on them and how strong? I'm going to go with the number one cause of plant problems and say too many nutes.

mid to bottom leaf chlorosis and new growth that looks like the picture?

The post and title are confusing to me.

Also, I see 5.7-5.9 PH so are we in coco or hydro?

Your right that in confusing. On the new leaves mid way to bottom of them. I'm running full high pressure aero. No media. I sprayed coco wet, magic green, khoas bloom, cal mag, and nutes at 6.0. Now that I type that out. That's a heavy foliar plus res ec at 2.5

heat damage?

i think you hit it yourself, 2.5 ec is high to begin with, then you're foliar feeding on top of it? i foliar feed as little as possible, may do it if something gets severe, but if you're on top of your plants, you should never really need to foliar feed. roots are designed to absorb nutrients, leaves were designed to exchange gasses, if you keep clogging up the stomata foliar feeding, its like you're water boarding your plants, not quite drowning them, but making them work to breath

I believe that makes perfect sense. I'll work on not babying them too much foliar feeding is a double edged sword.

I'm a great believer in foliar feeding. I alternate using weak solutions of fish emulsion, seaweed extract, and RO water. I get fantastic results. I don't think it was the foliar causing the issue. I would get some sticky traps to check for critters. I've never burned my plants with foliar except the one time I accidentally sprayed them with bleach. I have however toasted a few with root feedings when I got a bit too heavy with it.

i don't think it was the foliar feeding by itself, i think it was the foliar feeding on top of 2.5 ec.
and i do think if you do too much foliar feeding, you start to clog your stomata and choke the plants...

Yeah I think it was a trifecta of issues. High ec water, high ec foliar and when the light was on. The New growth looks fine but I'll keep an eye on it. Thanks everyone for the help.
