OK. I'll admit, I suck at diagnosing problems. I've looked at all the stickies, followed links to external sites in hopes of figuring this out without having to bother you kind people for what I should be able to figure out on my own. But here I am, still unable to figure out the problem.

Only one of my plants is affected. She's a Mandala White Satin (strain known for its abilities to take the heat). She's 6 weeks into flower roughly 20" tall. Current temp in the room averages about 75f.

She is currently not on nutrients because I have too many plants on too many cycles to be able to keep track accurately. I stopped nutrients about a month ago. When she was on nutes, she was given Fox Farm's full liquid and soluble feeding schedule dosed to half the recommended amount and fed every other watering. The soil she is in is Fox Farm Ocean Forest. Since taken off the nutrients, she's been given clean water only: tap water sat out for at least 24 hours for the chlorine to evaporate then I adjust the pH aiming to get between 6.4-6.6. I'm not sure of the PPMs.

I'm attaching a pic of every leaf affected on the plant. She's been having this issue for about 2 weeks now and it's getting worse. All the leaves affected cover the entire height of the plant, but if I remember correctly, the leaves started showing a problem towards the top of the plant, not the bottom. New growth is still forming and it seems that only the fan leaves are affected.

Thanks for all your help! :bigjoint:

I'm bumping again. Someone's gotta know what's going on. Normally, I would just wait til someone answers, but my plant is getting close to death, so I'm desperate!

You torture a plant through starvation and you want help????? You didn't feed it for a month. During flower no less.

Before being dick about you can try being at least halfway nice.

I "starved" ALL 18 of my plants for a month and this is the only one that's affected. I've also grown 4 crops of nute-free plants before and never had this problem. Have you ever "starved" a plant before? If no, I will not accept your answer as you don't actually have experience with nute-free grown plants. I acutally really hate it when people think plants absolutely have to have nutrients. No, the nutrients help make the buds bigger, better, and more potent. Not keep it alive. How do you think pot grew in the wild for the first billion years of its existence before humans invented nutrients?

And yes, I waited a month before asking because unlike some people who flip out over the tiniest problem, I realize that a lot of leaf problems are minor and do not need to be tended to. I also acknowledge the fact that the problem could have been temporary and was waiting to see how it progressed. Originally, I thought it was too close to the light (about 4" away from 400w HPS), but now that it's been a bit further from the light (7" away) a week now and it's still getting worse is what prompted me to seek other help.

Ever hear of the process of elimination? If I don't know what's wrong with my plant, I try one thing at a time so that I can figure out the problem instead of bombarding it with everything I can think and never fully knowing what fixed it. That way, if I have the problem again, I know exactly what it is. Plus, if I don't treat for every little problem, then I don't create new problems by giving it too much of something.

Which leads me to the main point of why I haven't reinstated the nutrients. Because most people on this forum think nutrients are the answer to everything. Well what if my problem stemmed from giving too much nutrients? Then I say "oh no, my poor plant looks like it's starving, I better feed it more" Problem worsens. I can't even tell you how many times I see people on this forum who have nute-burned plants then try to fix it by giving more nutes.

Now, let's say you're right and it does need nutes. Instead of being so cute with a smart ass response, you can be helpful and say "it really needs more N, P, K, Magnesium, Potaassium, Iron, Zinc"... and/or any of the other 100 things that could be wrong with it. This is the first plant I've had with a major problem. I have no idea how to diagnose and I'm here for help. Not shitheaded remarks which show your lack of knowledge on the subject as well.

Thanks, I actually did use this chart before to try to diagnose, but since this plant seems to have many of the problems listed, but none of those problems fall under one category, I was having trouble determining. Do you think it could be more than one problem? I'm having such a tough time because of all the plants I've grown (over 100 total) I've never had anything remotely close to this happen, I'm just baffled. If you could please indicate what you might think, I'd really appreciate it because, like I said, I've already been to many different websites and I just can't bring myself to any conclusions.

Thanks again.

Wild. I just logged in to try & find the solution to the exact same problem. Also growing in FF OF and using FF nutes - just BB so far. Auto dwarf at about 4 weeks...she's in flower, don't know how long as it's my first grow and I'm not keeping track as I should (now I know). In two days she's gone from looking great and healthy to most leaves crumbling and the ones that aren't look just like your post. Watching & will report back after I scour the threads!

Cool. Well, not cool. But I'm glad to see I'm not alone! When you say 'BB' do you mean Big Bloom or Beastie Bloomz? Do you have photos of yours? Post them up here too!

Two questions:
- Does that soil contain slow release nutrient why you are not feeding any nutrient to your plants manually?
- Are you allowing your pots to completely dry between watering?

Sorry, I wasn't being a dick any more than I can help. You clearly don't need any advice. Good luck.

ok im no expert grower but had a similiar problem and what i was told was that it has to do with the heat build up in the air and how much the plant photosynthesis the plant give off which is at a high rate at being to hot and fans blowing on plants..the plant cant keep up dries out all the moisture in the leaf which makes it wilt .dry and die......when you dont water your plant they go in a state of shock.and the roots are looking for water plant may get tall and thin with weak stem ...water them babies man give them nutes....they ll respect you more ..if you didnt feed me for a month and i was your kid youll be on your way to JAIL...

- This is what Fox Farm says about the soil

"[FONT=Verdana, Arial, Helvetica, sans-serif]Ocean Forest® is designed for container planting. It contains sea based ingredients and perlite for better aeration and drainage. Our customers tell us that Ocean Forest® is the finest potting soil they’ve ever used, and because container plants depend entirely on the soil they’re grown in, that’s important.[/FONT][FONT=Verdana, Arial, Helvetica, sans-serif] The soil is pH adjusted to 6.3 to 6.8 and are nutrient rich. It has a specific nutrient, humus, earthworm casting and peat moss content that make it ideal for its particular use."

- I go by weight when I water. If they feel light, or a few hours away from being very light, then I water again. But I don't wait til the leaves start sagging.


Also, to those that recommend the nutrients again. I planned on starting them again eventually, but I was waiting til the different plants were on similar schedules. It's a long story, but basically I was watering 1 plant on one day with week 5 nutes, then the next day would water 3 plants on week 3, 2 on week 6, and 1 on week 7. This was going on consistently for about a month before it got very hard to handle. I have a calendar which I write down details that I do every day to keep myself from getting confused or forgetting. I work two jobs already, I couldn't keep up with it. Anyway, explaining how it got that way would take a lot longer, and I don't want to bore everyone.

I just have one question. Over the past 3 days, the watering schedule is a lot more under control, which is when I planned on starting nutes again. So my question is, I usually start flushing 2 weeks before harvest (which is how far this plant is). But I remember hearing that Fox Farm is organic soil and that you don't have to flush it. I flush anyway, just to be safe. But do you think it's safe to do all the way up to the day she's cut down? Is FF really organic, or did I receive misinformation?

Thanks 8)

I do need advice, just not smart as remarks that serve no purpose. It's one thing to be condescending when you give your advice and offer nothing to back it up or fix my problem. It's another thing to tell me in a more adult manner what I'm doing wrong and make suggestions on how to make it right.

I don't think my remark served no purpose. The answer is as plain as the nose on your face. You haven't fed your plant in a month. Ocean Forest's nutes are not going to sustain a plant through flowering. Those nutes are depleted. Your plant has nothing to eat.

Feed your plant; that is my advice. You can read this as condescending because that is how it is intended.

it is a PH PROBLEM without doubt. it is just showing up worse in this plant than the others. it is probably to late for this plant to do any kind of recovering . ALWAYS MIX PLENTY OF DOLOMITE LIME IN THE SOIL..FOR ALL OF YOUR PLANTS. ph will lock out nute uptake of the plant and starve it.
ive got a buddy that always has PH problems and this shit shows up from time to time on his plants. have you checked the PH of your soil run off>? if you are using some kind of MG soil the PH will be WAY TO LOW TO GROW MARIJUANA IN .good luck

Organic soil does not mean that it has organic nutrients in it. All soils are 'organic'. The list of stuff in the soil is not enough to sustain cannabis. If you have not been feeding your plants then you do not need to flush them since you ARE flushing them already.

Thanks for bringing this up. After looking around online some more last night, I found a site with a lot of pix that looked like mine and it was bad pH. I went to the store today and got a soil pH meter (I have a test kit, but I only used it before transplanting). I figured if the soil pH was good and the water pH was good, there would be no reason for it to go up or down, no?

Anyway, I came home with the meter and the soil on that plant is getting a pH reading of 7.0 where all my other plants are ranging between 6.4 and 6.6. So I determined this was its problem. I read that I can just flush it with some lower pH water to get the soil pH lower, but if I'm already watering with water between 6.4 and 6.6, then how would the pH have gotten to 7.0 is the first place? What causes that to happen?

I was referring to the nutrients when I said that, not the soil itself. ;) I know I've technically been flushing for the past month. I was just wondering that since the nutrients are organic if anyone would recommend me starting them again this late in flowering. I wanted to make sure what I read about organic nutrients being used up until the day of harvest being safe was really true and see if that's the route I should take.

They are fairly safe to use, but like chemically derived nutrients, if you over feed with them your buds will taste like shit and you will need to flush again or a long cure.
