Bugs or what?

[Colliedude]

Now a new problem has emerged in my garden

Do you recognize these weird spots on my leaves? The plant is otherwise quite healthy, bushy and growing at a normal rate, which leads me to think that this is some kind of infestation.
And yet I cant find any bugs, eggs or anything like that.

Some info on my grow:
Strain: Ice (from female seeds)
Age: 23-25 days (veg)
lights: 115 Max Grow Cfl, 150 W Hps
Medium: 70 % Sphangum peat moss, 15%vermiculite, 15% perlite, 1 tablespoon dolomite (liter)
Temps: around 26-27
Runoff-PH: 6,2-6,3
Nutes: only 50 % of the prescribed dosage of Canna Vega
Light cycle : 18h Hps & Cfl, 6 h only Cfl

Thats about it.I hope you can help me figure this thing out
peace






Full plant pic, as you can see it looks pretty darn healthy

I dont think its critters . Can you give us a pic of the bottom of the leaf ?
also how much circulation do you have in your space ? Is the fan blowing on her directly for a long peroid ?
thanks

 

[Colliedude]

Here are some pics I just took,
the last too are blurry because my cams zoom sucks

The air circulation is good, I have a fan blowing on them all the time, and the grow room is vast with plenty of fresh air coming in all the time

Is it just that one leaf ?
does the fan hit that leaf hard ?
it looks like a lower leaf coud you have droped alittle water on it durring feeding or watering ? This can have a magnifying affect from the light
are you seeing any white or brownish red spots on the leaf that are about the size of pin head ?
What was your previous problem ?

Is it just that one leaf ?

No not only that leaf, 2 more are affected but the spots are barely visible on the other 2.

does the fan hit that leaf hard ?

The fan IS a bit strong, yes, but it is an oscillating fan so it isnt hitting the plants all the time.

Hm...interesting, it is very possible. I sure hope this is a result of a magnifying effect, dont want no bugs in my grow room, It took my 2 freaking days to disinfect the grow area before I started the grow.
No brownish red spots, only the white ones you see in the pics.

What was your previous problem ?

Nute deficiency. I used a preferted mix and waited too long before adding additional veg nutes

 

[SouthernSmoker]

well from what i have gathered from your pics and your desciption i would suggest two things .
see if you can back the fan off just a little the leaves should shudder alittle not get blown too hard {I can't see your room so just a guess]
two see if you can raise the ph just alittle try and get the run off @6.5 if you can . Iuse to run my nutes at 6.2 and had all kinds of problems with nute lockout moved it to 6.4 and they cleared right up .

Hope this helps, keep us posted

those spots l00k like mites. little white spots like that mean that they are sucking the juices of life out of them but i can only see a small spot on the leaf. keep a close eye on them the next few days. ive never seen ph be the reason for white spots on leafs

 

[Colliedude]

Would higher humidity levels worsen the problem or make the bastards go away? (if it IS an infestation) I have a Cool Mist humidifier which could help me increase humidity dramatically

 

[SouthernSmoker]

hey 420kushmaster good to see ya mang !!

there are a few spots that look questionable that for sure
but the big ones look like a nutrient problem to me .

Collidude
are you seeing any white or brown little pin size spots on the leaves that you can move with your fingernail ?
well if you are or you are not it wont hurt them to spray them down with a good neemoil bath!

Hey man if you can get the temps down and the humidity up that is the key to mites .They thrive in high heat and low humidity they will reproduce very fast in those conditions. if you keep the temps down and the humididty up this will slow there reproductive cycle down for you to kill the litlle fuckers .

Neemoil ,sm90, safers soap all will kill living mites by suffacation and wont hurt your plant .
even if you dont see the little fuckers then spraying can help keep them away !!!!
preventative measures work out for all in the end

 

[Colliedude]

no no such movable spots are visible.
neemoil? cool, now I just have to find out what that is in my language

Awesome just what I wanted to hear! Time to plug in the humidifier then!

Ph is a little high for soilless. Adjust fertilizer water ph after mixing to about 5.8 to 6.

Plants look fine, and I see no evidence of bug damage, at least not the ones your worried about like mites or thrips.
