sPOTTS ON LEAVES 3 WEEKS INTO FLOWERING

hEY EVERYBODY i JUST NOTICED THIS DISCOLORING ON MY la WOMAN THAT IS 3 WEEKS INTO FLOWERING, ANYBODY HAVE ANY IDEAS WHAT IT IS?

Do you find this throughout your plants or localized to one plant or even one leaf? What the min, max temps for you room?

It seems to be only on one plant, and only on the leaves around the middle of the plant. The temps are 78°F during the day to 55°F at night.

I think it might be nitrogen def because of the the flowering nutes. I am giving her the entire line of Fox Farm nutes and following the feeding schedule provided at half strength so she gets nutes every watering.

dont use nutes every watering

even at half strength, usually you want to use nutes then water then nutes then water..

listen to the plants and i think you have nute burn or a magnesium def.

nitrogen def. your leafs would be turning yellow

That really looks like light burn to me, although you report it on the "middle leaves". Light burn is not always at the tippy-top closest to the light though -- the leaves have to develop out to a certain maturity to be capable of blowing themselves up under too much light. I have had very similar light burn about 1/4 down the plant where the biggest, most fully fledged fan leaves were.

If you're feeding with every watering,you're feeding too much.

Only on one plant and this damage is on the middle of the plant. Assuming the other plants are the same strains then the possibilities could be over lighting or over nutrient(but no other plant has this problem) or some sort of pest like spider mites especially how they look like tiny necrotic spots. Time will tell.

Hard to tell by the pics, but it could be something as simple as spidermites(which aren't simple at all.LOL). Turn over one of those leaves and look closely, you will be able to see the tiny dark colored mites on the underside, if that's the problem. If not, at least that's one thing eliminated form the list, and a bad one at that.

Could you try to go though Imageshack and post those pics in full size? It's free to do, and would help us identify the problem alot easier.

I moved the light up another 6in, and I will fix the feeding schedule. I also noticed some whiteflies but there are only a few I dont think it's them.

Try and do a night observation on your plants to see if anymore friends come out to play.

Hey everybody thanks for your help here are some newer and better pics I think it might be a magnesium def but I'm still not sure, it seems to be getting worse but it's still only on one plant. It looks like it is only on the older fan leaves any more suggestions?

When in doubt, flush and start over.

Well today I flushed her with six gallons( I didn't pH the water but my water has been right around 7 anyway) and added 2 tsp/g of Epsom salts at the end. I will keep a close eye on her to see if she recovers. Once again thanks for all of your help!
