Small white spots, I see no pests anywhere, ideas?

Not sure what's causing them. Plants appear very healthy otherwise, but the leaves are all consistently showing faint, small white spots on all of them.

600W HPS, Subs recipe amended, they vegged outdoors until last week when they went under 12/12..

That little guy? don't worry about that little guy...

This was a branch that broke off my first batch, i rooted it and stuck it outside and this is what popped out - it smells fiercely dank, is covered in sugar, and has the weirdest leaf structure I've ever seen.. Also exhibiting the problem worse than the other plants it would appear.


The rest give a better idea of what i'm seeing. doesnt' appear to be a deficiency or overdose of anything that I'm aware of..

do you have a scope?

Yes, and a decent loupe, but neither are good for pictures... :/

*edit* fuck me, i see larvae.. Not sure if spider mites or thrips, do thrips live/breed under the leaves?

Time for some neem oil and maybe a batch of lady bugs..

yeah thrips will indeed live and breed under the leaves, take your loupe or scope and look at the underside of where those white spots are, i bet those are little eggs

They do look like eggs.. I don't see anything crawling around however.

i would say dont waste your time on lady bugs, but yeah i am sure they are thrips

Calcium Deficiency.

Good Luck on your Grow.

Since I can see the larvae, I'll still treat with safer or neem oil, but I do have some dolomite I can add to my next batch of tea, will give that a go and post back w/ results in a week or so.

Found mites the other day, treated with rubbing alcohol and water mix. Monitoring now to see if they return. Also I use cedar mulch as a cover, seems to help some with nats

Wiped all the leaves down real well, and treated with azamax.. Will apply a few more times in the coming days and see how things progress. I'm assuming because these little buggers suck on the leaves that the damage is done, but further problems should be reduced/eliminated.. Got a batch of humus/ewc/lime tea brewing now to hopefully offset any calcium issues. I drop 1 tbsp of molasses in the feed water every once in a while so I'm likely ok on Mg. Going to monitor that closely though as I suspect Mg locked out Mn in my last batch..

Also you can make a batch of habenaro peppers, garlic, and cinnamon... Blend 5 peppers, 2 garlic cloves, and a tablespoon of cinnamon into a quarts of water, heat UNDER a boil for 20 mins, strain and apply to leaf bottoms, this is organic and affective and also can be used on flowering plants. If u don't like the pepper stink u can also mix 4 tsp of 29% H2O2 per quart, add 2 tsp neem oil, and 1/3 tsp of dish soap, the spray kills on contact and the neem keeps them away, this needs to be done every 3-4 days until the eggs have all hatched.
