what bug could be doing this?!?

Wat could be causing this?my plants in flower are dying on the bottoms but are just fine on top.

That doesn't look like pest damage to me, from what I can actually see.

Do you actually see any bugs?

See something is eating them and u can only see em with a microscope but the top of the plants aren't affected...yet

When you take pics, it helps to turn the HPS lights off.

Unless you can get a micro shot of dem bugz, it's gonna be hard to pinpoint exactly what's causing it.
What do they look like?
Any webbing on your plants at all?
Any little white dots(eggs) or larvae?

Buy some sticky bug strips, hang em, and come back in an hour. That will help identify.

I just cut that of a bottom branchthe tops aren't dying but what's causing the bottoms to die like this

so how bout a pic of a leaf that's just starting to die......

No webs no larvae or eggs idk guys I'm stumped its only my flower room.everything in veg is just fine

I'm not seeing any bugs heere lately tho.any ideas?

Here lately I see no bugs could I

Could it be something other than bugs?

if you could get a pic that doesn't just look like a green and brown blur somebody might be able to tell you.......

I could tell ya that youre running your pots 2 dry....

You said you saw bugs dammit!

The pots also look a little small for plants that size.

It's probably overfed, I would try flushing it.

I can not see anything from you pics. As had been said earlier. Flush and water. On a pot that size and a plant that size where I am at it would need water everyday. Good Luck

You sir have rust mites. I had them just recently and couldnt find anything on the webs about it till I came to this site. I was petrified when the dude said he had to move away from his home to get rid of them. Well, he didnt have to do that. Get your scope and look at the infected leaf. you will see only at 30x magnification these little bastards. They eat the buds (also called bud mites). nothing kills them but pyrethrin bombs. Get 2 bombs , they cover 3000sq ft. its ok if your area is smaller. Set one bomb off with lights off one day, and do it again the second day back to back. Will not hurt your plants at all, may cause a little curling but will bounce back. Please heed the warning label of the bomb. Clean all your grow i.e walls, buckets, etc etc with bleach before you bomb and set them outside the contaminated area. Plants that are too far eatin up just toss out, if you want to save them, cut off all the dead crap and bomb them. The only thing that survived the bomb was spider mites, meh...go figure... But yea...dontwaste any more money on bug sprays, bomb it. I live in The Springs

It doesn't look like the lower leaves are turning yellow before dying, correct? (If they were, you'd have a nute deficiency) Here is a great chart to use for diagnosing nute issues, btw: http://www.weedfarmer.com/cannabis/tables_guide.php

I don't know that flushing your plants is going to do any good at all. I do agree that you need to re-pot. Your new soil should correct any nutrient deficiencies, or at least help quite a bit in the short term. In addition to hanging the sticky bug catchers, put some of the sticky catchers on the floor and/or on top of the soil (beneath the plant). They sell round sticky traps at Home Depot (buy the refill packs).

You can also just put out a bowl of water (add 1 tsp liquid soap detergent like Dawn), set it on the floor, and check it tomorrow. If it has critters in it, you know you have a bug issue. No money spent, and easy diagnosis.

One more thing: Do you have supplemental lighting that is getting to the bottom of your plants, the parts covered by the plant canopy? I cant' tell from the pictures, but your plants look like the lower portion of them are suffering from a lack of light.

Let us know how it goes!
