Crazy Bug, is it thrips or mites? or what?

[gnarly]

5Gal pots of FFOF
No Nutes Used (except a very light FF Grow Big foliar feed today)
2x600w Digital
4x8 foot area
32 clones, getting big tho, some up to 12 inches tall now


Ok guys, I have 2 plants that have a strange issue.

On many of the leaves there are yellow/brownish dots all over. Like as if I had a yellow pepper shaker and shook it on the leaves. I don't see anything on top of the leaves, so I look at the underside and I see these tiny black/white dots crawling very slowly. One of them had these dots around when we got them, but I figured it was a nutrient oddity.

wtf is it? I will get pics up soon.

EDIT: I have Neem Oil, should i spray heavily on these plants?


On another note, some/much of my plants have new growth that is very vibrant, but some of the leaves have tips that are going yellow/brown. Many of the new leaves after 2 days have the tips curling downward and inward, and become yellowed within another day.

Also on several of the plants the new growth or majority of growth is very light green (why i did the foliar feed). Some of the leaves are light green with dark green veins moving into them.

Help?

THE BUGS




THE HURTS

 

[gnarly]

Update, a pal of mine told me the hurts might be from ph. We've been feeding ph6.3 water (about), and runoff is like 7.1

I was unaware that the runoff was the goal ph.

We will use about 5.0 ph water next time and see where it goes.

Yep ph is too high. You want runoff at 6.3, the nice middle point of the acceptable range of 5.8 - 6.8. Your ferts should be 5.5 to get runoff to 6.3. As the ph gets closer to ideal you won't have to adjust your ferts so much to counteract. Plants do not like big swings in ph. 5 is too low.

It looks like you are burning those plants with your light. Looks like heat stress. How high are the lights? Those plants are kinda small to be under 2 600s. Also, HIDs have a hot spot directly under them, depending on the hood, this could be very intense and burn plants.

Dude, you have the dreaded mites, bad I'd say. Any fine webs?

Spray them ALL with neem asap, repeat every two days for 10.

You are better off feeding your plants through the soil. Foliar spraying invites molds and powdery mildew when the foliage is wet.

I totally agree with HeadyPete! And you definately have mites quite bad. I'd say to hit them real heavy with the neem oil asap<-----and you need to get the undersides of EACH leaf.... Your plants are small enough to get this under control now. As HP said, yo uneed to repeat this every couple of days to get them as they hatch, or if you miss some.
I am going into 5th week of 12/12 w/60 girls-------- I have the borg again. It's a bitch to spray all of mine. They(mites) build up tolerances to our sprays and get really hard to get rid of.
Other than Neem are some good products as well.... Ed Rosenthal's ZERO TOLERANCE is a great herbal-pestiside(except it only comes 'ready to use', no concentrate), and ORGANOCIDE. There are many "home remedys" here in the threads too.....

So as far as your mite problem, get it wiped out NOW!
Good Luck to you---and Happy Growin'

man i hope i dont get bugs like that

 

[gnarly]

Update: after the first heavy spray of neem there really doesn't seem to be any more signs of damage and seems that there are few/none actual living mites on the 2 affected plants. Tonight they will see another heavy neem dosage and I will be putting NoPestStrips in the room as well. If they seem to come back I plan to fight them with nature (predator bugs) first and see how that works.

 

[HeadyPete]

Be vigilant. The neem won't kill eggs, and if any hatch after you finish spraying they will reinfect the whole garden, and as growinman stated, they can build up tolerances to pesticides because of their fast reproduction rate and large numbers.
