Soil or other problem? Multiple plant deficiency?

Hey all..

I'm a fourth time grower who is giving it another go. I'm exactly 28 days into an indoor soil grow vegging six plants - Critical Kush, Super Lemon Haze and a random Blueberry strain given free. Using a 400 watt HID.

I'm used a Pro-mix (1 year old and new mixed 40/40) soil amended with the leftover 20% shared equally with worm castings and perlite. I also shook a little epson salt into the mix. And while I probably don't need to, my water is well and comes out of the tap on the hard side at 7.5, so I PH down with phosphoric acid to 6.5.

So while I haven't grown much, I have grown enough not to freak out. My other grows I've experienced a range of deficiencies and problems and learned quite a bit. Like what a cut worm looks like while it's wrapping around the stem and snuffing the life out your plant (which I was able to save!). In any case, I've provided pictures of a current problem which all three strains are sharing. ...as well as a jalapeno pepper plant which is sharing the same grow room (which is not ideal I admit). Since all plants are demonstrating this problem (light green / whitish dots prevalent to the top side of the leaves. Some are a bit shiny) I'm curious if this could be a soil problem.

Also for reference ..most of the plants are between 4-6 nodes except one of my Lemons which apparently topped itself and divided at the first node. These are in the second stage of transplanting and will ultimately end up in 5 gal containers with a different new Pro-mix based soil which will be amended. Since first transplant I've only watered once. Next feed will be first nute feed.

So any recommendations on what I might be able to do or not do would be totally righteous..

Thanks guys.

Looks like you've got some chewers. Check under the leaves with a scope. Those white spots? That's either mite or thrip damage.
Spinosad or Green Cleaner should get you right.

Yeah I agree, I have leaf hoppers on my outdoor plants almost looks the same. I wonder if a few spiders would help? Or just get some safe bug spray. I might have to as well.

Yes, whitish spots.

But nice.. I'll give that a try. I recently bought some straight Neem oil for some outside veggies I'm also doing ..and sprayed the inside girls with it today. Think a Neem treatment might work like that Green Cleaner you got in mind? Suggested for mites and various insect control.

Neem is used more as a preventative measure. A lot of folks use it as part of their IPM.
Green Cleaner kills mites and eggs. I've read reports of people using this successfully in flower too.
The other one is SNC17 and I think Flying Skull has an effective one too.
Whatever you decide make sure you saturate the plant top, bottom and surrounding area. If one of those insidious bastards survives the whole cycle starts over again.

Thanks guys.

I used a lens and got up under the plants and there are no signs of webbing/mites.

However i did find this little fella. It was sitting on the main vein for about 10 mins before moving on. Didnt see any others and i while they are tiny i scanned.

Also.. at any given time i saw maybe two or three little dark flying objects hovering around the plants.. maybe the size of a slightly used #2 lead tip. Anyway.. possible gnats?

That looks like a thrip. Spinosad will take care of that.

Ha.. will do Tangerine. Will take a couple days before i can get that kind of magnification.

Aphids ive seen before and they are usually larger than what i got in that picture. Also i'm not sure its larvae either because it moved around like it was crawling.

There are also tiny dark bugs buzzing my girls. Saw maybe half a dozen this morning a little sfter the light turned on..

What a bitch though.. not growing in a sealed up environment for the first time and this is what i get.. ha ha.. the pain...

Those black flyers are probably fungus gnats. Not as big a threat unless you get a nasty infestation. They chew off tiny root hairs, are vectors of powder mold, and get all stuck up in the buds, but they're fairly easy to deal with.
I get them once in awhile from soil, compost or EWC. Nematodes are good additions as well as some Bti beneficial bacteria from Gnatrol. Even those Mosquitos Bits/Dunks will work in a pinch but they have a lower Bti count. With fresh soil I do an initial drench with Gnatrol and rarely see them any more.

From the damage and the pic you posted I'd say its thrips. Captain Jacks Dead Bug Brew or Spinosad should clear those up.

You're right, summertime growing can be a total pain in the ass between the heat, humidity, and bugs.

Just got back from work checked out the plants and found three more. They like to sit (and probably feed?) right along the main vein so they blend in.. not to mention tiny. But i caught one moving along a leaf surface. Ill give that Spinosad a whirl. Should i follow directions to a T or is there a better method?

Thanks again

Yes. Follow label instructions and be sure your lights are off or very dim

My local all around shop actually had the Captain Jacks.

Yup.. thanks, i was planning on spraying when the lights are off tonight. How strong is this stuff on the plants though? I did a half tbs for a pint of mix.

Im 65 days in and the bug problem was fixed. Thanks again for all the input guys..

I just switched over to bloom two days ago and today noticed a new problem developing on only one of my two kushes. So far its only affecting two or three sprouts but multiple leaves. I just fed the girls three days ago at full strength bloom nutes and half veg so i plan on going water only on that plant for now. Im ph'ing my water between 5.8 - 6.5 and also fed her cal-mag (but its a 3 year old bottle of General Organics). And these bitches are killing water now.

Anyway.. whatever this is is affecting old and new growth. And up until now aside from a few lower leaf marks from some munchers all of my plants have remained very healthy overall..

Thoughts on new sightings?
