Spots on leaves..what are they???

[gogetta4293]

I'm about 6 weeks from seed, and 1 of the ladies has these spots on her...about 50/50 on the plant even on a leaf of the newer growth..mites?...thrips?....calcium?....nute def???...help! It was grown from seed in mg seed starter mix...now being watered every other with ff gb & bb...I haven't fed in about a week because I'm transplanting them into straight ocean forest tomorrow with a lil perlite added, and I know it's HOTT!...so I figured they get fed then..besides it's only on this 1 plants...thanks ahead...GG

It looks like early thrip damage. google pics of it, very similar. Soon you might see black dots around, thats their droppings. If you think it is spinosad will get rid of them fast.

I'm pretty sure BMP420gti is correct, and if its thrips spinosad is the way to go. Its hard for me to see clearly though and it kind of looks like mite damage. If they are tan dots then its mite damage, its they are more silverish and assymetrical its thrip damage. little clusters of black dots in the damage ae thrip droppings. take a look on the underside of the damaged leaves near the veins to see if you can find the culprit.

Ok I'll consider the spinosad...it's funny how I went to buy spinosad and the clerk suggested pyrethrin..so I bought it and some pure neem oil..but then I get home and everybodys tellin me to use spinosad..oh well back to the store...but 1st a little more research because I've also read that it could be light/heat stress...being that I have been leaving her outside in 90+ degree temps at only 4-5 weeks from seeds might have been a little too much considering the fact that when I move them back indoors every day, they go back under cfls for veg...and the spots are on certain foliage..I would think that the thrips would have spreaded maybe after a week or 2 of the spots bein there..same color, same size...no brown spots or anything yet...better safe than sorry though...GG

 

[gogetta4293]

Then again the spots do look asymmetrical to the veins so thrips may be the answer...hopefully not...GG

It isn't heat stress. 90 outside is nothing for them, especially at a month old. If you are taking them inside and out, it's even more likely insects.
When I said assymetrical, I meant not in relation to the veins, but in the shape of each blemish. If they are tiny round dots, thats more like mites, but if they are silver and assymetrical in shape then thrips.

thrips are not a big deal and spinosad should have them under control within a couple applications.
You may keep getting them if you don't eliminate the vector of contamination, but if you're taking them outside that may be hard to do.

i'm experiencing this is well I think its at the root zone I don't think its thrips on mine ...I'm also in Fox forest soil/light warrior which is known to come with bugs I just hit them with a ogbiowar foliar drench if that doesn't work im going to hit them with a neem oil drench and spray luckily i'm still in party cups it only seems to be affecting my sour strawberry starts all from the same bag of light warrior.

Thanks!..I'm gonna do the spinosad since it was said that neem nor pyrethrin wouldnt do the trick...also a neem soil drench....GG

I had a similiar problem on a small clone, ithas yellow marks like little trails. I looked at the under a magnifier and found what I think was a mite. I seen it moving kind of quick but tiny and roundish.

My immediate response was thrips. Easy to deal with and spinosad the way to go as has been said. Mites don't move quick yet thrip larvae can boogie and vanilla/cream colored and live on the undersides of leaves like mites. Adult thrips fly and can be mistaken for fungus gnats in a room. Thrips were a problem for me at times and more of a nuisance.

I had a similar problem, I didnt know what it was. I was on my 2 blue cheese mothers, I thought it was a nute problem so I left it. Then it started on my reveg blue cheese and I looked more closer at the underside of leafs and it was spider mites.

I sprayed everything down 2 times with Safer Miteicide and I put a NO PEST STRIP (home defence strip) i bought at Canadian Tire. They give off a pesticide vapor to kill bugs. (not the sticky trap) All new growth now is clear and fine. I read so much about the No Pest Strip that I think they really cleared up the problem fast. Im taking them out now for repackage until next out break. I had a bad problem, I didnt pay attention to it at first until I took clones and they were infested. I cleaned everything, and got the supplies I needed to start killing them.

I think it looks like mites. and I should know, we've been managing mites for about a year and a half now. it sucks, those little specks look just like what we got. get them NOW while there new

 

[BudBongJovi]

Those spots look like mites. The beige appearance is a result of the mites extracting the chlorophyll. If you look on the underside of the leaves, you can see the mites moving. Normally, you'd be able to take off the specific leaves with mites on them to control the spreading, but considering you're still at a young stage, try Fox Farms 'Bug Me Pyrethrin'

Cheers,

definitely two spotted spider mites neem and azamax are great to buile up plants internal defenses and the azamax is somewhat systematical making the mites starve and slow reproduction to a crawl
