what's this? (FLOWERING)

Hmm. This looks pretty rare. It's clearly not a N/K/P deficiency. My best bet would be a mild Calcium deficit. If not that, them some other mineral deficit. In any case, I'd get some molasses from a health store or market. 1tbs/1gallon. Fixes all mineral problems nicely.

What nutes are you using? What is your soil's pH? How often do you water with nutes?

ph.....nute burn?

That little burn at the very tip is typical nute signs for pre nuted soil. I wouldnt say nute burn but its showing signs of it. I dont think its anything to worry about. As for the spots?? Are you misting at all? What kind of PH meter are you using? Is it the one with the 2 metal prongs?

Molasses can be found at health stores. It's really healthy food, for people and plants. I doubt you'll ever find molasses at a grow store. It's usually used for human consumption.

It's normal for the bottom pair of leaves to start yellowing and withering away, especially during flowering, so don't worry about those. When the next 2 pairs start fading, that's when you should sound the alarm (unless you're in the final 1-2 weeks of flowering, when it's again normal for most of the leaves to yellow).

Boneman's questions gave me another hint on the problem. What are your temps? If they're too high and you like to mist your plants, the little drops of water ("Noo, not the little drops of water!") can heat up very quickly and also cause spot-like burning.

Thanks Boneman! You the man!
RastaCourage, keep us posted on the development.

I dont know about anyone else but,, that PH meter with the 2 long prongs to stick in the dirt that also measures light and moisture always read around 7 for me,,,, my plants were sick from very high PH and I didnt even realize it until I bought a real PH meter, then I found out my PH was around 9, so I fixed the problem,,,,, the moral of this rant is that (for me at least) that so called PH meter sucked and I also heard other have the same complaint.......GOOD LUCK WITH YOUR PLANTS......

hell yeah, those pronged ph meters suck ass IMO, lol. I use a good cheap liquid ph tester - GH makes a pretty decent one.

As far as the plants problem goes, it looks like a deficiency - maybe copper, iron, or a magnesium deficiency. im trying to look it up in my garden saver book, and all three of those types of deficiencies can result in the same type of signs your experiencing in the earlier stages. lemme read a little more, and see if i can pinpoint the problem a little bit better for you man. im no expert by any means, but i own alot of books n i read them, lol.

hope to help u out man

**edit** -- U know what man, its really hard to tell with the blurry pic to be honest, because now im checkin out the book, and it could very well be a form of nutrient burn too, lol. i know this shit here is confusing, but if i were you, i would try and actually use a balanced nutrient regimen, so you can keep track of what your feeding your plants, so its easier to identify the problem and correct it. my own advice to you, would be to flush out your soil, and then go out n get yourself a reliable line of nutrients - Fox Farm's trio of nutes works awesome, plus its really hard to burn your plants with them as long as you follow their feeding schedule.

im sorry i couldnt be of more help, but ill keep trying to help if there is anything that i can help with man. Sorry for contradicting myself, but like i said, your pics are a little blurry, and my second line of advice would probably work out the best for you.

Your temps are a bit high, but I still say, get some molasses and see if that works for a mineral deficiency, if not, its probably nute burn.

Keep us posted on new developments.

PS: a better pic would help us all see what's really wrong.

Yup..this was clearly nute burn, but your plant has grown into a big girl, she can take it now.

It's probably not mildew since, as you stated, they smelled nice, not rotten or spoiled.

It's also pretty normal during flowering for the second pair of leaves to fall off, although still pretty soon.

I guess the lesson here is, never buy soil with time release nutes. Oh, by the way, what % NKP is that soil releasing? I'm thinking, if the soil is releasing a certain ratio of NKP, your plant will not have optimal nutes for flowering or vegging (since these two processes require different NKP ratios and the soil has only one).

Keep us posted.

you can tell by the leaves it was nute burn?
you really are 'doctor cannabis' lol

the soil percentages are..

N - 0.07%
P - 0.01%
K - 0.03%

(jamaican bat guano)
flowering percentages are..

N - 1%
P - 10%
K - 0.2%

it was all i had at the time..
& i had to transplant that very day..
& the only soil i had was miracle gro & scotts potting soil..
never again though will i use the time-released..

if the problem continues..
i will be sure to keep this thread updated..
& post better pictures..

thanks for your help man

I presume that the worst is over. That bat guano is a really good addition.

Keep us posted if anything happens.

your being paranoid, let it grow

It is typical for a plant to shed her oldest leaves during flowering in order to offer the rest of the plant it's saved up nutrients. This will be especially clear during the last 1-2 weeks of flowering, when all leaves turn yellow.

What is your watering and feeding schedule?
