cal mag indeed

well maybe...............but thats not the problem........guess again

 

[Mr. Outdoors]

I am only guessing and would only throw this outthere because of the "guess again". It kind of looks like my first grow that I had brought in from the outdoors. I had a serious bug infestation.

what type of lighting are you using and how close to your plants is it? honestly it looks like you may have light burn from too much radiant heat

 

[mrbungle79]

i think woody might be hinting at spider mites but lets hear about the light situation.

 

[mrbungle79]

now that i look again light burn would only be near the top of the plant and your issue looks like it goes further down on the plant. woody may be right. check the undersides of your leaves very closely

 

[jbrown3]

i know he's hinting at a insect prob, but i honestly don't think its the prob. but then again im not some genius at diagnosing plants

light burn on a plant
spidermite damage

 

[Po boy]

grown mostly outdoors and cfl's at night. i've grown many and never burned by lights before. i keep the lights well away from the foliage.

 

[mrbungle79]

i would suggest grabbing a loupe and check for mites then

 

[Po boy]

i did have mites but spinosad got rid of them. i still check them daily. could the spinosad cause the mites to melt into the bottom of the leaves?

The darkening of the leaf tips leads to a different conclusion than spider mites.

edit: Checking my grow bible for you. Will update if I find relevant info.

Do you spray anything on your leaves?

This is during veg right?

What nutrients and soil? This could likely be toxicities not deficiencies.

Is it appearing on new leaves?

they're in flower with about 3 weeks left. the problem started during early flowering.
