help with spotted leaves

[mrblue]

Hello, i have been reading and looking and just cant figure out what is causing this. using pbp,sweet,and a little hydroplex with tap water.
dont know my ppms or ph at the moment as my meters are not calibrated correctly. (will get some calibrate fluids today ) . any help would be appreciated. been using suggested levels and dont think i have really been over feeding.

Did it start with a light speckling? Check the undersides of the leaves for Spider Mites.

seems like it just happend over week or so period maybe... i didnt see any mites or web looking stuff..
here is underside of another one

Mites are hard to see with the naked eye. I deal with the Borg on a daily basis and my leaves had a speckling like that. The only other thing I can think of that speckles leaves is much worse than Mites ... I don't even dare say it on the boards as I don't want to give it Any power. Check your rep ...

i will look again for the mites with the scope tonight. but i have two big buckets side by side and the other one i dont think looks as bad. here is a pic of the other side , and they are also different strain... you can almost see the difference in the two buckets but its not a great picture.

didnt see no mites with mag and light.

I also think that looks just like mite damage. If it's not, you'll know in a bout a week, because mites will start making tents if it's them. If not, I'm stumped, unless it's a reaction to a foliar spray.

If not mites it looks like a calcium problem maybe?

Did you get the comment I sent with the + Rep hit? I'm hoping it's mites ... and I wouldn't wish them on anyone. If it isn't mites or what else I have suggested then I'm clueless.

wats hydrplex?

my thoughts exactly. It looks like (to me) a cal/mag def. due to pH lock out. I would get that pH meter calibrated asap and test the run off after giving pH balanced water (with no nutes). I had a problem that looked just like that from my first grow - and I had no pH meter at the time, turns out my runoff was 3.9!!!

If persistant it could perhaps be tobbacco mosaic virus - looks kinda like pictures I saw of that

Do you flush them, maybe now would be a helpful time. In your first post there is a leaf pic with deformity, have you seen this before? Is it only on your indica plant? Is it common in Veg or Bloom only?

/agree

what's your medium? how often you using that pbp and what dose? the fact that the 2 strains are not equally affected could mean one is taking the beating you been givin better than the other...helps to know your start water ppm, and ph depending on the medium - get those pens working!

edit: if you're having what looks like Ca deficiency it could just be locked out, check the sick plant sticky for what locks out Ca, cuz u may be giving too much of that.

we've all had the BORG, look closely the damage is not the right color. it's burnt, not eaten.
