I get this def. EVERY time... VERY frustrating!
    #391152 - 03/28/10 03:57 PM (6 years, 11 months ago)

I am generally a newb with this being only my 4th crop, but EVERY time I start to flower the plants, this same exact deficiency rears its ugly head.



I thought I had it pinned to either P or K because I had a similar problem during veg and I bought some GH KoolBloom (0-10-10), and it seemed to fix it. However, when I switched to flowering this happened again. I am even adding the KoolBloom EVERY watering, and they're still fading.



The most affected leaves are neither at the tom nor bottom, but rather, in the middle of the plants.



Could it be that I am feeding TOO MUCH? I feed every watering which is about every 3-4 days.



Or is it possible that mites are causing this? I see no actual mites but there are small deposits on the bottom of the leaves that look similar to salt. Also, there are no webs around the leaves like with what happened the last time I had mites.



Any help at all is GREATLY appreciated.

It does look a little like mite damage to me.  Can you get me some more pictures of the undersides of more leaves? 

But it also doesn't look like that's the only problem that your dealing with, if you do have a mite issue.  How big are the containers your plant's are growing in?  Have you flushed at all??  If your feeding at every watering you could be dealing with a toxic salt build up.  Or just a nutrient toxicity.

Nah, you can get rid of mites entirely with a repeating dose of pyrethrum bombs.  One a week for 3 weeks.  Just make sure that all electrical equipment is unplugged and off before activating them.

Here ya go..

So what you're thinking is that the symptoms of the salt buildup gives the mites a weak part of the plant to exploit and that's what I'm seeing?

I'm using Flora Nova Bloom (every watering), GH KoolBloom (every watering), GH Diamond Nectar (every watering), General Organics CaMg+ (every 2 wks), Earth Juice Microblast (every watering), SaferGro Manganese (every 4 wks). And then SaferGro organic pH down when needed.


I'm not good with the camera, especiialy with the Macro on. So if you need anymore pics let me know and I'll get them up right away.

You definitely have mites man.

How long into flowering are you?

I ask because that's going to determine what you can use to take care of the mite problem.  Now when it  comes to the nutrient issue.  I think you need to start off by flushing your medium.  You should flush at least 3 times the amount of soil your in.  So if you have 5 gallons of soil your going to have to run at least 15 gallons of water through it.  If you can get a product like clearex that would be your best bet.  If not a VERY light nutrient solution will work better than plain water at flushing the built up salts out of your medium.  After that resume your feeding at the next watering, but don't feed with every watering you do.  At least ever yother time at most.

Awesome, thanks guys! I am only a week into flower.

I'm safe to use Neem oil then, right? Isn't Neem oil safe to use up until two weeks before harvest?

here's what I found to be a nice non-toxic mite killer. plus, not a chemical so there's no possible way for them to acquire immunity to it.

- Buy some diatomaceous earth

- Rub all over plant leaves. I'm talking EVERYWHERE

- Watch the little bastards all die within the next week

- ????

- Profit

Yep, D-Earth is completely safe for humans and plants. in fact, you can even get "food-grade" stuff which is even safe to eat :shrug:

yeah, the gnats is where I started to use it, but I found out that it works just as well for mites :thumbup:

Had some winged root-aphids a couple weeks ago, knocked those fuckers out in 3 days by just sprinkling diatomaceous earth all over my medium

The white stuff on the underside of leaves are mites/eggs/ and shit. Pyrethrum will not kill all mites and is far more toxic than neem oil. Mites quickly gain immunity to pesticides and that is why they are so hard to get rid off.






My understanding is that Natural Pyrethrum is apparently not toxic for humans and it supposedly breaks down extremely quickly when exposed to light. Therefore, it would seem that natural pyrethrum is not a terrible option if your in flowering.

I have used pyrethrum to combat mites and I think it's effective. I have also used it within two weeks of harvest - the smoke was good and I didn't die or get sick. I smoked a lot too. :shrug:

I was discouraged from trying neem oil because I read somewhere around here it really stresses out your plants and it makes your bud taste like dick.

Sweet, I got a considerable amount of DE from my myco-endeavors. I love owning multi-purpose products. I think I'll do both.

Flushing all those girls was a huge pain in the ass. Guess it's worth it, though...

Also, how fast should these girls respond to the treatment? I sprayed pretty heavily and flushed like a mad man with Final Flush/water solution.

However, they seem like they're still getting worse. How long should I wait after the flush to commence feeding again.

Also, would mychorrizal and bacillus inoculant such as Great White combat mites in the dirt? I'm going to use it either way, but it seems like bacillus would kill the bugs and the mychorrizae would protect the roots from moderate salt buildup.

I highly doubt that I'm underwatering them. Especially now with them just recently getting flushed.

I have them in 2 gal. bags and am doing SOG from clones that I let veg 1 week after transplanting to soil and then switched to 12/12.

Part of the problem with half the plants could just be that they're Blueberry strain and are a bitch to grow, anyways...
